Why Doesnt This C Program Crash?

[wmcbrine]

Portable to everywhere with a C compiler. Even gcc doesn't fully implement C99 yet. C89/C90 is its default mode, for good reason. (Of course it also supports all kinds of gcc-specific extensions in its default mode.)

Again, I'm suggesting C89 (ANSI C), not "K & R" C (which implies pre-ANSI).

Thanks, ansi and gnu99 works well

Another thing you can do with C99 is

//C99 has C++ comments and variable declarations in for loops
//(you don't have to separate declaration and usage)
for(int i=0; i<lol; ++i)

/*C89 hasn't*/
int i;
for(i=0; i<lol; ++i)

Well, the GNU89 implementation does allow the C++/BCPL-style comments...
