I finally got totally stumped, but it's not on something hard.
Lil help so I can sleep before Santa comes?

What is wrong with this?
Code:
#include <stdio.h>

int main (void) {
	
	int cnt;
	
	for (cnt = 4; cnt == 0; cnt--) 
	{
		printf("%d\n",cnt);
	}
	
    return 0;
}

It just don't work on Xcode.
