Friend : Hey bro I made an awesome program which shows your future wife's name.

Me : Hey that sounds interesting, show me the source code bro !!

Friend shows the code :

#include <bits/stdc++.h>
using namespace std;

int main()
{
string first_name , last_name;

cout << "Enter your first name\n";
cin >> first_name ;

cout << "Enter your last name\n";
cin >> last_name ;

cout << "Your wife's name is " << "Mrs " << last_name << "\n";

}

Me : Dude you are gonna crack Google some day :P

HE:"Hey I improved my code"

ME:
*opens the file*
*Sees random static allocations*
*Code is as verbose as before*
*Down to 2600 lines from 2800ish*
*Still doesn't do shit properly*

"Uuuh what exactly did you do?"

*Starts noticing the lack of namespaces*

HE: "I used this using namespace std to write a bit less"

ME: "Can I pay you yoga lessons so you can taste your own cock and show your parents how good you are at it?"

using namespace std;

#include <iostream>
using namespace std

int main();
{
cout << "Hello devRant!"
}

A programmer walks into a bar. He has a concussion because you were using namespace std and didn't scope to building.

Now I'm concerned that using std as a namespace can be seen as offensive by people who are carrying an STI.

A 'using namespace std;' in a FRIGGGINGG FRIGG LIBRARY HEADER.
"Yuh, I'm totally the king of multiverse. F*** me, right"

Will this code be compiled ?

#include<iostream>
using namespace std;
int main(){
int 🥩=1;
int 🧀=1;
int 🥬=1;
int 🍞=1;
int 🍅=1;
int 🥪=🍞+🥬+🍅+🧀+🥩;
cout<<🥪;

return 0;
}

#include <iostream>

using namespace std;

int main() {
cout << "Hello world" << endl;
}

If it works, It's time for a coffee break!! :)

Have you ever written a very complicated code to look like a professional programmer??

For example:hello world app in c++

#include <iostream>
using namespace std;

int main(int argv, char argc)
{
char vhWnd[] = new char[13];

struct dataentry
{
string txt;
float vex = 0.2345234;
};

vhWnd[1] = 'e';
vhWnd[4] = 'o';
vhWnd[3] = 'l';
vhWnd[2] = 'l';
vhWnd[7] = 'o';
vhWnd[5] = ' ';
vhWnd[6] = 'W';
vhWnd[9] = 'l';
vhWnd[8] = 'r';
vhWnd[13] = '\0';
vhWnd[10] = 'd';
vhWnd[12] = '!';
vhWnd[11] = ' ';
vhWnd[0] = 'H';

for ( int i = 0, i=13, i++)
{
nhttp << vhWnd[i];
}

return 85037593;
}

I don't "using namespace std;" because it makes my code look more confusing to others and may make them more hesitant to ask questions.

#include <iostream>
using namespace std;

int main() {
int t;
cin>>t;
while(t--){
int n;
cin>>n;
int arr[n];
int count=0;
for(int i=0;i<n;i++){
cin>>arr[i];
count^=arr[i];
}
cout<<count<<endl;
}
return 0;
}

In the above program,
how does this code snippet work?
count^=arr[i];

AOA friends please help me to solve the program of C++

#include <iostream>
using namespace std;

int main() {
int passengers = 126;
int empty_seats = 0;
//passengers =126;
passengers after 1st bas leaving= passengers - 50;
passengers after 2nd bas leaving= passengers - 50;
passengers after 3rd bas= passengers;
empty_seats= 50 % passengers;
cout << "Empty seats in last bas"<< empty_seats <<endl;

return 0;
}
