Official /prog/ XP Thread

In this thread, we will write a high quality program by all working on it at the same time. You must not write a line that causes a compiling error. You can only remove a line after writing a proof that it causes a bug.
// A

int main(void)
{
    // B
    while(1)
    {
        // C
    }
   
    // D
    return 0;
}

// E

You can add lines at A, B, C, D or E. You can write atmost 3 lines per post.

The program currently has no output, and never exits.

Alright guys, I know you told me not to link to specific files, but please check out my section on productivity: https://github.com/affiszervmention/permadeath/blob/master/PRODUCTIVITY.md

I really think it is evolving into something beautiful, it should get a place in a /prog/ sticky of sorts, I really do think so.
