Someone on a C++ learning and help discord wanted to know why the following was causing issues.

char * get_some_data() {
char buffer[1000];
init_buffer(&buffer[0]);
return &buffer[0];
}

I told them they were returning a pointer to a stack allocated memory region. They were confused, didn't know what I was talking about.

I pointed them to two pretty decently written and succinct articles, the first about stack vs. heap, and the second describing the theory of ownership and lifetimes. I instructed to give them a read, and to try to understand them as best as possible, and to ping me with any questions. Then I promised to explain their exact issue.

Silence for maybe five minutes. They disregard the articles, post other code saying "maybe it's because of this...". I quickly pointed them back at their original code (the above) and said this is 100% an issue you're facing. "Have you read the articles?"

"Nope" they said, "I just skimmed through them, can you tell me what's wrong with my code?"

Someone else chimed in and said "you need to just use malloc()." In a C++ room, no less.

I said "@OtherGuy please don't blindly instruct people to allocate memory on the heap if they do not understand what the heap is. They need to understand the concepts and the problems before learning how C++ approaches the solution."

I was quickly PM'd by one of the server's mods and told that I was being unhelpful and that I needed to reconsider my tone.

Fuck this industry. I'm getting so sick of it.
