So there is this girl who was trying to be cute and wrote a mock C code for me :

She wrote :

If(existence=disapointment)
printf("kill self");
else
printf("what else??");

And without hesitating I told her that her code had a fault in it and it would always print "kill self" no matter what the level of disappointment is. And asked her to fix it.
The way she fixed it was probably best described as the situation when you have no idea what you are doing and you don't try to understand either. (or was simply passive aggressive) :

If(existence=disapointment)
printf("kill self");
else
printf("kill self");

Honestly though I hope she was being passive aggressive because boy do I pity people who confuse between '=' and '=='

How my C programs may as well be written:

#include<stdio.h>
int main() {
printf("Segmentation fault\n");
return 0;
}

Back in the days when I started to learn c I had an assignment to print all the prime numbers between 1 to 100 but didn't know how (with if/for/while)

So I searched Google for "prime numbers from 1 to 100" and used printf to print them on the screen

I got an A+

What my lecturer think I have learned:
- Programming Patterns
- C, C++, Java
- Socket programming, web programming
- Operating system...

What I have actually learned:
1. printf("Hello World");
2. echo "Hello World";
3. console.log("Hello World");
4. Console.Writeline("Hello World");
5. cout << "Hello World" >> endl;
6. System.out.println("Hello World");
7. puts "Hello World";
8. "Hello World"
9. write("Hello World");
10. Display "Hello World"

She: We've been together for so long and why are you never romantic??
Me: What do you mean? I can say I Love You in 10 different languages!
She: Awww... Really ?!?
Me:
cout<<"I Love You!";
printf("I Love You!);
System.out.println("I Love You!");
print "I Love You!"
echo "I Love You!";
say I Love You
puts "I Love You!
msg db 'I Love You!'
<h1>I Love You!</h1>
dbms_output.put_line ('I Love You!');

Me: Hello.. ?

me:
#include<stdio.h>
main() {
printf("Hello World");
}

Today was fucking awesome!

I always wanted to do a project in C++ since I've been more of a Java guy for years now.
And today, I finally wrote a full console program in C++! (For windows, it's a .exe)

The purpose of that program is to show if a file has a file lock on it (because of copying for example).

It started as simple as that, but got complicated quickly:
- It needs colors! So I added colors.
- Just a single file? Boring. I need wildcards, so I can put a * for anything in the file name! Jup.
- Just one directory? Boring. I need a recursive directory walk! Got it.
- But wait! There has to be an option to switch between recursive and wildcard/single mode! So I checked if the first argument equals "-r"! Hacky but works.
- Oh uh... that spams a lot now! The purpose was to show locked files, so I need another argument to specify that I only want to see locked files! Damn now it get's hard... I need a Linux-like command line argument parser (this -h and -s "hello" stuff). So I took the opportunity to write one myself! Done.
- Refactoring everything to use my new fancy parser...
- Adding more and more arguments, just because I can:
- "-d" hides "access denied" messages
- "-l" shows only locked files
- "-r" activates recursive directory walk
- "-f" formats everything nicely, basically printf("%-150.150s | %s", filename, locked); a maximum width which get's truncated if too long so everything lines up nicely
- "-h" which of course displays the help page
- "-w file" watches a file, if the file is locked it will refresh every 500ms, if it's still locked nothing happens, if it's unlocked, the program prints "unlocked" in green and exits. And yes, it does have a rotating line (something like this: "-" "\" "|" "/" "-" and so forth...)

That project was just awesome to make. I learn languages fastest if I just do a big project in them, and today, I really learned a lot.

Thank you for reading all this!

My first code :-
#include<stdio.h>
void main()
{ printf("Hello Divya"); }

Output :- I have a boyfriend...

HoD in my college is a "22 year experienced C programmer" with a PhD in CS.

One day I went to him and told, it is very hard to work with TurboC, and it isn't needed as we can easily migrate to GCC.

He asked me why was I complaining. No other student has any problem. They have been using it ever since the college started and everyone was "comfortable" with it.

I stood silent. He then went on to say, even JVM was coded in TurboC. I nodded and left the office as i didn't have an argument.

He's the same guy who had earlier said, "printf returns an array of characters printed", so I guess everything works here.

It's when your teacher gives you an 8 out of 8 grade for literally one printf and one scanf program that you realize the average level of your class is ridiculously low.

Canadian C:

#include<stdio.h>
#define eh ;
main() {
printf("Hello World") eh
}

I tell him to submit a pull request, he just merges his code. I revert it and tell him to submit a pull request, he submits one then merges it himself immediately after...

If you're gonna comment a lot or a little, at least be consistent. I just read some code like this:

//prints "are you ready?"
printf("are you ready?");

//get the value
int findVal(int x) {
/* some fucking complex algorithm with no comments whatsoever that seems to have an error messing everything up */
}

My first code:-

#include<stdio.h>
void main() {
printf("Hello Priya");
}

Output:- I have a boyfriend!

First step of creating antivirus,

void main() {
printf("✅Scan Complete.

Happy Christmas in C!

So my classmate just decided to write "printf("Suck my balls I dont remember how to do this);" in a programming exam and forgot to delete it before handing it in.

Well... after saying "sorry" like a hundred times the teacher accepted his apology.

if (eidAlFitr.today())
printf("Happy Eid\n");

main()
{
printf("Hello devs");
}

#include <time.h>
char*w = "AAAA########+++///9999AA Good %s!\n\0Morning\0Day\0Afternoon\0Evening\0Night";
int main(){time_t t=time(0);return printf(w+25, w+w[localtime(&t)->tm_hour]);}

I'll use this topic to segue into a related (lonely) story befitting my mood these past weeks.

This is entire story going to sound egotistical, especially this next part, but it's really not. (At least I don't think so?)

As I'm almost entirely self-taught, having another dev giving me good advice would have been nice. I've only known / worked with a few people who were better devs than I, and rarely ever received good advice from them.

One of those better devs was my first computer science teacher. Looking back, he was pretty average, but he held us to high standards and gave good advice. The two that really stuck with me were: 1) "save every time you've done something you don't want to redo," and 2) "printf is your best debugging friend; add it everywhere there's something you want to watch." Probably the best and most helpful advice I've ever received 😊

I've seen other people here posting advice like "never hardcode" or "modularity keeps your code clean" -- I had to discover these pretty simple concepts entirely on my own. School (and later college) were filled with terrible teachers and worse students, and so were almost entirely useless for learning anything new.

The only decent dev I knew had brilliant ideas (genetic algorithms, sandboxing, ...) before they were widely used, but could rarely implement them well because he was generally an idiot. (Idiot sevant, I think? Definitely the idiot part.) I couldn't stand him. Completely bypassing a ridiculously long story, I helped him on a project to build his own OS from scratch; we made very impressive progress, even to this day. Custom bootloader, hardware interfacing, memory management, (semi) sandboxed processes, gui, example programs ...; we were in highschool. I'm still surprised and impressed with what we accomplished.

But besides him, almost every other dev I met was mediocre. Even outside of school, I went so many years without having another competent dev to work with. I went through various jobs helping other dev(s) on their projects (or rewriting them), learning new languages/frameworks almost every time: php, pascal, perl, zend, js, vb, rails, node, .... I learned new concepts occasionally (which was wonderful) but overall it was just tedious and never paid well because I was too young to be taken seriously (and female, further exacerbating it). On the bright side, it didn't dwindle my love for coding, and I usually spent my evenings playing with projects of my own.

The second dev (and one one of the best I've ever met) went by Novo. His approach to a game engine reminded me of General Relativity: Everything was modular, had a rich inheritance tree, and could receive user input at any point along said tree. A user could attach their view/control to any object. (Computer control methods could be attached in this way as well.) UI would obviously change depending on how the user could interact and the number of objects; admins could view/monitor any of these. Almost every object / class of object could talk to almost everything else. It was beautiful. I learned so much from his designs. (Honestly, I don't remember the code at all, and that saddens me.) There were other things, too, but that one amazed me the most.

I havent met anyone like him ever again.

Anyway, I don't know if I can really answer this week's question. I definitely received some good advice while initially learning, but past that it's all been through discovering things on my own.

It's been lonely. ☹

That moment when you receive an email saying

"I got an error message that's says 'All hope is lost, delete everything'. Is this normal?"

and you have to explain that was an old printf that you put there for debugging purposes and forgot to remove it before committing...

How to teach a 5 yr child to code?

The method is simple you don't need to teach him to code just help him to understand the method to execute a task. It took me years to understand that coding is a way to express what you want to say- the method and also is our expression. So, if you can help him/her to understand what to express, then I believe the method on how to express is totally unworthy. He/she can say printf("I know this") or print("I know this") or #I know this or he/she may create a new language.

- Hell yeah, the memory leak is caused by the code that checks for memory leaks. But fucking how
- Finds out the leak is caused by the implementation of the std C lib
- In the fucking printf() function
- Proceeds to cry

Yknow what the best part about Unix is? (Not Linux. Like old school Unix. AIX, HPUX, or in this specific case: Solaris)

It never needs to be updated. like ever. Even when new features are added 5 years ago to add features that GNU has had for literally decades. Updates are for the weak. Because why should I be able to type "netstat -natup" when instead you can enjoy several hours of developing the nightmare one-liner that is:

Pfiles /proc/* | awk '/^[0-9]/ {p=$0} /port/ {printf "%.4s %-30s %-8s %s\n", $1,$3,$5,p}' 2>/dev/null

Isn't that just so much more fun?!
Thanks guys. I'm going back to GNU now if you don't mind.

Today I experienced cruelty of C and mercy of Sublime and SublimeLinter.

So yesterday I was programming late at night for my uni homework in C. So I had this struct:

typedef struct {
int borrowed;
int user_id;
int book_id;
unsigned long long date;
} entry;

and I created an array of this entry like this:

entry *arr = (entry*) malloc (sizeof(arr) * n);

and my program compiled. But at the output, there was something strange...

There were some weird hexadecimal characters at the beginning but then there was normal output. So late at night, I thought that something is wrong with printf statement and I went googling... and after 2 hours I didn't found anything. In this 2 hours, I also tried to change scanf statement if maybe I was reading the wrong way. But nothing worked. But then I tried to type input in the console (before I was reading from a file and saving output in a file). And it outputted right answer!!! AT THAT POINT I WAS DONE!!! I SAID FUCK THIS SHIT I AM GOING TO SLEEP.

So this morning I continued to work on homework and tried on my other computer with other distro to see if there is the same problem. And it was..

So then I noticed that my sublime lint has some interesting warning in this line
entry *arr = (entry*) malloc (sizeof(arr) * n);
Before I thought that is just some random indentation or something but then I saw a message: Size of pointer 'arr' is used instead of its data.

AND IT STRUCT ME LIKE LIGHTNING.

I just changed this line to this:
entry *arr = (entry*) malloc (sizeof(entry) * n);

And It all worked fine. At that moment I was so happy and so angry at myself.

Lesson learned for next time: Don't program late at night especially in C and check SublimeLInter messages.

Oh man where to start:

Not wanting to use LINQ because he did not wanted to "download external dependencies"

Not wanting to use prepared statements on their php sql code, and refusing to use pdo because they will "always use mysql"(moved to postgreSQL shortly after I left)

For some reason including a php file that only had ?>......thats it....only ?>

Use c++ but refused to learn oop and use structs for everything, importing stdio.h and printf everything.....like really?

Maybe just nitpicking, but refusing to use the recyclerview pattern on am android app. The implementation was faster after I made the change.

Importing a library for promises instead of using the ones already in the language(JS)

Changing the style of aaaaall p tags instead of using classes as well as refusing to use divs in place of p tags...well...fuck

Not indent his ASP classic code

A C++ question. Correct answer will get you a virtual thug glasses & a cigar if you're into that , and upvotes (:

#include <stdio.h>

int main(void) {

int i = 4;

int* p = &i;

i = 8;

printf("i divided by *p is: %d\n", i/*p);

return 0;

}

What is the result of running this code?

some people are just worst than the devil.

int main()
{for (int i=0;i<5;i++)
{for(int j=i;j<5;j--)
{printf("*");
}printf("\n");
}
}

(some dude from class wrote that)

Enough is enough! I can't do it anymore!

Today’s lesson in C programming:

DON’T use
system( “clear” );
in Mac OS...
Causes seg Fault in ur program when it is perfectly correct...

What happened was... a friend wanted help with C programming and had written this code... but it was getting seg Fault randomly... just random seg Fault when his code was correct...

I pinpointed the seg Fault to a printf statement but the statement was correct...

Off to search the issue I went, found out that flushing problems can occur in printf if u don’t use \n.
This happens randomly. Thought this might b the reason...
Went to a VM running Arch Linux and tested the code there... worked perfectly. No issues whatsoever.

From a distant memory I remembered some people discussing to never use system( “clear” ); since it causes issues.
Thought to remove that line from code, thinking it wouldn’t make any difference.
Well imagine my shock when the code worked fine after remove that freaking line...

M gonna blame this one on Mac OS since arch had no issues with it 😡😡

Now to find alternative to system( “clear” );

Damm it I spent 4-5 hours on this crap!!!!!!

In fact I'm a sinful dev, so that I can't easily decide which one is worst. From indenting with tabs, or using nano instead of vim/emacs, to hardcoding database credentials on server, to many hacks and workarounds I use as actual "fixes" when the deadline is upon me and I've tried all I could. But it always led only to my own regret. For instance, my latest sin was that I prefered Debian over Arch and used proprietary graphic drivers to speed up my new setup. But ended up with a curse from St. Ignucius. (check my last rant)

But my worst sin probably goes to when I was "printf-debugging" some issue for a GSM controller on a raspberry pi. I forgot to remove one little print line and deployed the new "fixed" version. I didn't follow that project after that for like a month or so, when the client posted back the device and said that "it just doesn't work anymore". It seemed that raspbian didn't boot beacause the sd card was curroptted. I dd'ed through the card and I noticed that there are billions of lines of "DEBUG:: reading stream from 192.some.shitty.ip", took almost all over the 32G sdcard. Just as I suddenly remembered the cursed line I just added a month ago, I declared the sd card dead with no hesitation, dunce-commented the line (so the history would remember), implemented a time out for the thread containing it, setup a journald unit for my service and removed the redirection of process output to a log file, found a new sd card and installed everything again, and finally posted back the new "fix" to the client.

Moral: Never comfort yourself for the sins you have commited in the past kids, they certainly will come back to you. And also not to do any io especially write to a file on an SD card with ext fs, in a potentially infinite loop with no timeout.

P.S: I'd posted my last rant just before the new week rant last nigh. I really liked the St. Ignucius meme so decided to create a new one. He's very adorable :)

int main() {printf("Hello World!");}

Success! 🤦‍♂️

TIL there are linux manpages for printf and all that stuff.

printf("Hello World");

my code went into an infinite loop of printing "fuck". that happens when u forget to put curly braces and the first line after the if statement is printf("fuck\n");

Our 10th grade computer classes in school consisted only of writing 1 printf statement in C, which earned you an A.

Fav function is printf() in C.
Because sometimes, it's the best debugger.

Me: Do you know how to use a debugger?
Friend: printf(something);

Working on a C project right now, this is the only thing that comes to mind...

Good old printbugger.

When you search for this error during 3 hours

if (false);
{
printf("why u right ?");
}

And it was just the first lines comma

So, I accidentally hit a tourist near the bus stop. He shouted something in french in anger. A guy near told me he is abusing.

In anger, I shouted , " printf bi*ch" ..

An interesting python function I just made. Probably not the first to do so.

def printf(fmt, *args):
print(fmt, args, end="")

"If you run printf(“hello world”);, it will print “hello world” every time. But if you call a Windows API, God only knows what will happen."

I remember the first time our class coded a simple program in C. The objective was to input two random numbers, check which one is larger, and output it on the screen.

After class, I asked one of my classmates if he finds the test easy. My classmate replied that it was so easy he got bored. Then when I asked him to show me his code, this was what I saw:

int a, b;
printf("Enter smaller number: ");
scanf("%i", &a);
printf("Enter larger number: ");
scanf("%i", &b);
printf("Larger number: %i\n", b);

Mind of a programmer in an Interview be like:-
Interviewer:- What's your name?
Programmer:- My name is Alice. (In mind printf("my name is %s ",name);)
Interviewer:- Where are you from?
Programmer:- India. (In mind location = &India;)

When I start a new project in Python after not doing Python for a while:

print("Hello, World.");

When I start in C:

printf("Hello, World.")

After errors: *facepalm* *facepalm* *facepalm* "RRRRGH semicolon."

Heh at least this time I remembered that Python uses print(), not printf()...

#include <stdio.h>

I just finished designing an entire asset management pipeline and christ on a fucking pogo stick, if it isn't convoluted.

Theres a lot of game engines out there, but all of them do it a little different. They all tackle a slightly different problem, without even realizing it.

1. asset management

2. asset change management

3. behavior change management

4. data management

5. combinatorial design management.

6. Combinatorial Behavior management

7. Feature completion

ASSET MANAGEMENT is exactly what it says on the tin.

ASSET CHANGE management can be thought of handling the import, export, formatting, platform specific packing, and versioning (including forking) of an asset.

BEHAVIORAL CHANGE management is a subset of asset management, because code is a subset of assets (depending on how you define 'assets'). The oldest known example of this is commenting and uncommenting code.
Or worse, printf debugging.

This can be file versioning, basic undo services, graph management of forks and mergers, toggles for features or modules, etc.

DATA management is about anything that doesn't fall into the other categories, everything from mission text to npc dialogues, quests, location names, item stats, the works. Anything you'd be tempted to put in a database, falls under this category. Haven't yet seen many engines offer this as an explicit built in tool as of yet, because the other problems are non-trivial as is, so this is a bit of low hanging fruit that gets handled by external tools, or loaded from formats as simple as json.

COMBINATORIAL DESIGN management is the idea of prefabbing, blueprints of broader object design using nested prototypes of existing game objects, to create more complex, reusable set pieces. Unity did this well. GM does this in part.

COMBINATORIAL BEHAVIOR management is entity-component systems, plus tooling to make it easy to add, remove, and configure components and their values on entity blueprints, also not uncommon. Both stencyl and unity do this. GM has a precursor to this in the form of configurable fields, but these fields are not based on component scripts attached to objects.

FEATURE COMPLETION is that set of gameplay mechanics or styles of design that an engine naturally makes easier to include or build in a game.

I don't think I'm aiming for all that, but I think at minimum a good engine has to do asset management, behavioral change management, prefabs, and entity-component systems with management tools for that. And ideally, asset change management.

Debugging with printf...

honestly some online courses are bullshit. i joined one for some sample code, and no comments, no explanations, the variable names WEREN'T even descriptive.

this is from a website with a published book… how about you take some fucking responsibility for your code?

the language was c++ and they are still using printf! shake my fucking head. you have global variables that are one fucking letter! please, stop, get help.

        }
    }

    public static void executeCommand(String command) {
        try {
            Process p = Runtime.getRuntime().exec(command); // Run the process
            BufferedReader stdInput = new BufferedReader(new InputStreamReader(p.getInputStream())); // Get the output
            String s; // Print out the output
            while ((s = stdInput.readLine()) != null) {
                System.out.println(s);
            }
        } catch (IOException e) {
            System.out.println("You're screwed, just use Java and get over it. " + e); // UR SCREWED

So this PHD fresh graduate work in our department for a year boast about how professional a PHP developer he is. Today, he , my the other 2 co-worker and I have to submit the project, He technically "Taichi" his responsibility away and said he can't do this and that. Expect we do everything for him. What is more sad, is as a PHP as he boasted, He dont even know how to use Xampp, apcahe.

Our CMS messed up because of him, Server are F***ed , he keep sabotaging our source code that works, and made one of my coworker cried due the stress he given. He keep telling us that how professional he is, how suck we are. Ironically, he as a professional , he can't even do the basics like even know echo" something "; can also printf("something"); in PHP. He said he studied in US and from Jordan. I know that people like me only have Olevel in Malaysia. So dont show off to me a foreign certification that can't even help you to complete the job.

I hope this project can be complete without this guy. All show and no go. Where's the team work tho?

Back when I was at university, during the first lesson of web development class, our teacher said: “If you have any doubt or problem, please ask me. The only stupid question is the one you don’t ask!”

A fellow student raised is hand and asked how to do printf in Java (it was totally legit as most of us only used C at that point and it was our only reference in programming).

Our teacher: “What kind of fucking stupid question is this?!?”

😳

My manager believes every bug can be solved by adding a thousand printf(s) and checking which part of the code isn't being hit. How do I politely tell him to get his shit straight? 😂😂😂

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <time.h>
#include <sys/time.h>

void setDate(const char* dataStr) // format like MMDDYY
{
char buf[3] = {0};

strncpy(buf, dataStr + 0, 2);
unsigned short month = atoi(buf);

strncpy(buf, dataStr + 2, 2);
unsigned short day = atoi(buf);

strncpy(buf, dataStr + 4, 2);
unsigned short year = atoi(buf);

time_t mytime = time(0);
struct tm* tm_ptr = localtime(&mytime);

if (tm_ptr)
{
tm_ptr->tm_mon = month - 1;
tm_ptr->tm_mday = day;
tm_ptr->tm_year = year + (2000 - 1900);

const struct timeval tv = {mktime(tm_ptr), 0};
settimeofday(&tv, 0);
}
}

int main(int argc, char** argv)

if (argc < 1)
{
printf("enter a date using the format MMDDYY\n");
return 1;

Alright, understood...

When it comes to the idea of programming and magic, or the comparison between software developers/engineers, computer scientists etc as magicians or wizards, nothing brings the idea much more close to hearth than the C programming language.

A while ago I read the R.A Salvatore books concerning Drizzt, the dark elf. I loved the books, have not continued reading them but I remember them vividly. There was one book in which a human magician came about wielding extremely explosive magic, humans were capable of channeling large amounts of it through explosive and unwieldly ends.

This is the same feeling I get from C

Consider:
int items[] = {1, 2, 3};
printf("Third : %i\n", 3[items]);

and fuck me if shit like the above is not dangerous, it makes sense, arrays have the first items of it server as the pointer address to a first element, doing the above operation returns the third element of the array of 3. But holy shit if I don't think this is dangerous and interesting as fuck

there are many more examples I have that I am finding through me fucking around with: language development (compiler, interpreter), kernel programming as well as net sec. C is the most powerful and devastating thing we have in our hands indeed.

What is everyone's goto to-do list tool/app and why?

I made test library a bit happier. Rainbows, fires and happy faces. Before the happy faces i had traditional dots. This is more cancer. I like it. My applications looks much more modern now.

The emoticon list is made by gpt but i've added a simple search function that finds an emoticon if you put a part of the description. It doesn't have to be exact. printf("%s",remo_get("books")) for example.

I need a life

You know shit is going to hit the fan if the sentence "c++ is the same as java" is said because fuck all the underlying parts of software. It's all the fucking same. Oh and to write a newline in bash we don't use \n or so, we just put an empty echo in there. And fuck this #!/bin/bash line, I'm a teacher. I don't need to know how shit works to teach shit. Let's teach 'em you need stdio for printf even tho it compiles fine without on linux (wtf moment number one, asking em leaves you with "dunno..") and as someone who knows c you look at your terminal questioning everything you ever learned in your whole life. And then we let you look into the binaries with ldd and all the good stuff but we won't explain you why you can see a size difference in the compiled files even tho you included stdio in the second one, and all symbol tables show the exact same thing but dude chill, we don't know what's going on either.
Oh and btw don't use different directory names as we do in our examples. You won't find your own path, there is no tab key you can press to auto-fill shit.
But thats not everything. How about we fill a whole semester with "this is how to printf" but make you write a whole game with unity and c#. (not thaught even the slightest bit until then btw)
Now that you half-assed everything because we put you in a group full of fucks who don't even know what a compiler is but want to tell you you don't know shit and show you their non-working unfinished algorithms in some not-even-syntax-correct java...

...how about we finally go on with Algebra II: complex numbers, how they are going to fuck up your life, how we can do roots of negative numbers all of the sudden and let you do some probability shit no one ever fucking needs. BUT WHY DON'T YOU KNOW EVERYTHING ALREADY HMMMMM, IT'S YOUR SECOND LESSON, YOU WENT TO SCHOOL PLS BE A MATH PRO ASAP CUS YOU NEED IT SO MUCH BUT YOU DON'T NEED TO KNOW PROPER SYNTAX, HOW MEMORY MANAGEMENT WORKS, WHAT A REFERENCE IS AND PLS FINALLY FORGET THE WORD "ALLOCATION" IT DOESN'T PLAY A SINGLE ROLE YOU ARE STUDYING SOFTWARE DEVELOPMENT WHY ARE YOU SO BAD AT ECONOMICS IT MAKES NO SENSE I MEAN YOU HAD A WHOLE SEMESTER OF HOW TO GREET SOMEONE IN ENGLISH, MATHS > ECONOMICS > ENGLISH > FUCKING SHIT > CODING SKILL THATS HOW THE PRIORITIES WORK FOR US WHY DON'T YOU GET IT IT MAKES SO MUCH SENSE BRAH

When you’re fundraising, it’s AI
When you’re hiring, it’s ML
When you’re implementing, it’s linear regression
When you’re debugging, it’s printf()

$egg = 1
$sperm = 1;

if ($test != 'TRUE') {
print "No Baby.";
} else {
foreach($eggs as $egg)

Programmer Birthday Cake quote ideas anyone?

At the moment all we could come up with was:
printf("%d\n", ++(betty->age));

But it's just so cliche.

printf("should i further my learning in python? what would you suggest for game development?")

Considering most IDEs can autocomplete basic things like function names, would it be beneficial (for learning purposes at least) that a language avoids ENTIRELY any abbreviations?

For example, let's take some of C's printf family.

Instead of fprintf, printf and sprintf, the new function names would be something like print_formatted_to_filestream, print_formatted and print_formatted_to_string respectively.

Sooooo the computers at my university

printf("%f", 0.5);

Just wondering what did I miss.
I missed this place a lot. My poor netbook from last post is on its final few moments. Got new hardware, finally. Now, I'm learning more and more.

printf("Hello World!");

printf("Hello World");

fn main() {
printf!("Hello World");
}

When you write print(string), which type of people are you:
A) 1. ( 2. string 3. )
B) 1. () 2. string
C) Autocomplete guys
D) hodor

*applies for echo, printf, println, etc.
** python2 and c++ are discriminated on purpose

started with
printf("Hello World... It's 2010")

Journey to
cout
println
Document.write
echo

Stayed at
try:
print('hey there...')
except:
print('got issue.... Fu#k this bug')
pass

for (size_t day=0; day < Inf; day++){
printf("I hate you Windows, I am switching to
Linux!");
pause (4hours);
printf("I love you Windows (=^..^=) ");
}

Printf("Hello world");

#include <stdio.h>

int main() {
int b = 2;
printf(b | !b?);
}

I don't really remember... That can mean one of two things... It was to long ago... Or don't know how to do it yet... I do remember my first programming class, when my teacher said, "you just need to do a printf ..." And I asked, "what is that?" He looks at me, eyes wide open, for a huge amount of time, and then left without answering...

a side note, it was university class.

What's your favorite bug you've ever created? Here's one that took a few hours from my life:

if (errCode);
printf("Something bad happened!");

It keeps failing, and yet it all seems like it's working!!!!

like = 0;
if( youare == "awesome")
{
like = like + 1;👍
}

If( like >= 30)
{
getstickies();😍
}
else
{
printf("Oops!! Next try!!!!");😫
}

Do you think you have to go to school for that? No no no. Some definition from a book won't help you, nor a person who haven't seen the real code for some time.

Sit and write. Anything! Still nothing? Printf("Hello World"); make conditions, think big, break the shit out of it and you'll learn along the way.

And do backups of git on remote. Two at least!

Javascript: console.log("the truth");
ActionScript: trace("almost the truth");

I took a Diploma course just before my graduation started because I was coming from a non IT background (Business and Accountancy) from a local institute. And the owner of the institute personally taught me C and C++. I had done some C in my school but it was just Printf and Scanf. And that man, taught me that the best way to write a program is to imagine it as a story. Since its C, so its all about functions and shit, so he made me understand that why a particular thing needed its own functionality. He inspired me to find the why. I learned that its important to keep the how in your perspective, but always have the why before how. This thought process made me feel that, since then, I've only learned newer ways to write the program, but my basic understanding still focuses on why.
:D

I use the ICU format often for translation because it's simple enough and supported on many platforms. It's something of a standard so I can use the same translation string format and similar library functions everywhere.

ICU is like a really simple templating language, somewhere between printf and something like smarty or twig simplified and specifically intended for internationalisation.

I updated a library providing ICU compatible parsing and formatting for one of the platforms I'm using and find tests break. I assume that only thing to change is the API. ICU very rarely changes and if it did it would be unexpected for it to break the syntax in a major way without big news of a new syntax.

The main contributor of the library has changed since some time last year. Someone else picked up the project from previous contributors.

Though the library is heavily advertised as using ICU it has now switched to using a custom extended format that's not fully compatible and that is being driven by use case demand rather than standardisation.

Seems like a nice chap but has also decided for a major paradigm shift for the library.

The ICU format only parses ICU templates for string substitution and formatting. The new format tries to parse anything that looks XML like as well but with much more strict rules only supporting a tiny subset of XML and failing to preserve what would otherwise be string literals.

Has anyone else seen this happen after the handover of an opensource library where the paradigm shifts?

Started with Codeforces. Some solutions in Python exceeded time limit at test #25. Wrote the same code in C++ but this time it exceeded time limit in test #33.

What’s the solution to this ? Replacing cin/cout with scanf/printf doesn’t seem to make much of a difference.

C: printf("Your message");
C++:cout>>"Your message";
Java:System.out.println("Your message");
Python:print("Message")

So this is something that happened in the first year at college.
I was at one of the top 50 engineering colleges in my country. To get admission here one needs to get a good score in the qualifying exams.
Now we had a cs related course in the first year which covered basic programming and coding concepts.
So in the first practical session we had to just write a hello world program in C.
The guy next to me for this session was the class topper who had secured the highest marks in the qualifying exams.
Now, as most of us know that program has a line that is:
printf("Hello World!"); or a variant of this.
This guy gets stuck while writing this line, so I ask him if I can help him.
He turns to me and said, " Man, I'm trying to get this comma to go up but it's not working"
Extremely confused I look at his terminal, only to realize that he was pressing shift+, and trying to get the " sign.
That guy went on to finish with a 4.0 gpa and is currently doing his masters.
Although hilarious, this serves as a very good lesson to all the beginners out here.
If you learn from your mistakes and improve you can definitely succeed in your life!
Just remember to actually look at the full keyboard though!

Bloody fucking Android! Updates, updates and more updates! My development Nexus 5X won't allow me to sideload apps since it updated... Hello, printf debugging! Goodbye, profiler and debugger!

My hate for Android grows with each version after 4.0.$something... 2 was shit, I missed 3, 4 was OK, and since then it's going steeply down.

And don't get me started on Material Design...! Good luck figuring out what's a button and what's a label...

And what's up with the "let's keep all apps running all the time to save a few ms on start" philosophy!? Who thought that is a good idea!? Yeah, System.exit(0) works, but... Is it so hard to determine when it's not needed anymore (has no services running etc.)? Why should a web browser (for example) stay in memory after I quit? Minimize is a thing (Home button), why make it so confusing?

Another thing - feedback-less async tasks - why? I like to know when it is working in the background... How the hell am I supposed to find out if it is supposed to do this or if it is frozen?

And Android deciding to kill your process whenever it pleases without any callback... Happened to me once with an Activity in the foreground (no exceptions anywhere in my app, it just quit). How do you do IO properly? It seems you can't guarantee some file or socket or something that must be closed doesn't stay open (requiring to restart Bluetooth 'cause the socket wasn't closed, for example)...

If C was developed in 2016 , most of the people would have understood "printf" as "printf*cking" 😂😂

No matter how many times I use it, I still have to look up how printf formatting works every so often...

A v dumb C language question....

Consider this code snippet:

{
while( getchar() != EOF )
printf("a");
while( getchar() != EOF )
printf("b");
}

Is there some way to get inside the second loop? After I input some text, ctrl+D sends in the text stream and loop 1 executes, then the control waits at the test for loop 1 again, pressing ctrl+D again triggers EOF, but it ends up skipping all loops after

printf("My First Rant");

My colleague, while debugging a bug:
If (var == 3)
{
printf("colleague name var=%d",var);
//existing piece of code
}
I asked why are you printing the variable value here.
He: "just in case"

He is 3 months more experienced and got promoted last December. Mine is delayed. I met my PM.
PM: You aren't this, You aren't that...
What I heard:
*You aren't licking my boots*

I always love when I pick C again just for fun. I'm really used to "print" something if I'm not sure about that in basically everything.

You wanna print something in C? Well unless you know what and where it is (no point of print-checking then), it'll just happily crash without any reported error. Not to mention if I wanna find a bug, I don't have to get a debugger! Printf alone is basically a breakpoint! Ah stupid me :D

Your aurix tricore is amazing for all safet systems... On paper.

Your support is abysmal. Tried forums, support line to verify a demo that only seems to work sometimes.

I just wanted to get ethernet communication using the demo. But hey one week gone and no success....

And the code seems to behave differently for each run :| the debugger works only on global variables and no printf statements. But hey just make a lot of globals right? So little footprint available so not possible :-\

Hoped that some forum could confirm the demo so I knew I was just making a fuck up, but cannot get that verified...

Embedded programming not for me... :/

I don't know what's happening. In passing a char pointer to a function. I'm having issue, so I'm printf'ing the address pointed to by the pointer. Right after I assign it, it contains the right address, but the printf on the next line has it containing a different address. Another printf shows another different value, but all the following printfs show that third value. They're all consecutive printfs with nothing happening in between in the program, and the char* starts it's life as an array. All compiler optimizations are disabled. I don't know what's happening, it's just randomly changing. 😭

I need help structuring a new TypeScript project built on a MERN stack. I used CRA for the client, so I opted to have separate tsconfig files -- one for client (auto-generated by CRA) and one for server (extends node12 tsconfig). However, I'm trying to setup eslint and prettier globally so that the lint/style rules are uniform across the codebase. CRA adds an eslint config that extends react-app, which is fine, but I'd like to still have my global rules. I have written my eslintrc.json file and am happy with it, so I placed it in the project root directory. I figured I would install eslint, prettier, etc. in the project root, then when I run eslint globally, it would lint the server code with the global rules and the client code with the global rules and the react-scripts rules.

However, react-scripts complains that I've installed a newer version of eslint in a parent directory. I can either ignore that rule or use the same version as react-scripts, but it seems like react-scripts is going to run eslint on its own when I run npm start, regardless of if I have a global config. What should I do? Is there a better way to structure the app?

My team's doing an internal hackathon this week focusing on improving developer productivity and happiness and I haven't been able to settle on an idea yet... Any help appreciated!

My question is"which value of 'a' and 'b' will give me output '1' not '0'?

C language's code is below here

#include<stdio.h>
int main()
{ float a=1.2,b=10.7;

printf("output is = %f",a&&b);
Return 0; }

Why we don't write dereference operator while priting string(format specifiers is %s).
For example: char arr[5]={"char"};
printf("%s",arr);//print char.
If we write like printf("%s",*arr);//compile time error.
