Random C Stuff.

While browing through comp.lang.c found this interesting discussion.

/* Without using /, % or * operator, write a function to divide a number by 3.
 * */
#include 

int divideby3(int);

int main(int argc,char **argv)
{
	int res;
	res = divideby3(9);
	printf("%d",res);
	return 0;
}

int divideby3(int aNumber)
{
	div_t d = div(aNumber, 3);
	return d.quot;
}

Never have explored the capablities of stdlib. Infact, with C Programming
Language out of touch for so many months, I was thinking this program will
seriously fail, thinking kind of how come div_t datatype, d.quote
(object.property ?) etc. gcc will crib saying dont using c++. But it worked
perfectly fine.
