So what does this look like to you:

#include <stdio.h>
#include <strings.h>

int main() {
	int a,b;
	void callMe(int x) {
		printf("callMe called with %d\n",x);
	}

	a=4;
	b=6;
	callMe(9);
	printf("a is %d\n",a);
	callMe(10);
	printf("b is %d\n",b);
	callMe(1);
	return 0;
}

No nesting in C?  Really?
