Why doesn't this end

#include <stdio.h>

main()
{

    int a;

while(a != 256)
    {putchar(a);
    a++;}
}

But if I add  a = 0;  after int a;, it ends fine?

Something to do with a variable not being initialized properly, and therefore, not being able to be compared or something?

Compiled with Code::Blocks+GCC or mingw or something. The debugger also reports no relevant issues with the initial code.

There is no explicit reason why it doesn't work. You're retarded.

If it's implicit that variables are initialized to -max, then that is a convention of the language.

OP is stupid as fuck, but this is not why.
