C Brain Teaser For The New Year

[gerard4143]

One day while pondering about C I came up with this program. Can you predict what the answer will be? Now run it, were you right?


filename.c

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char**argv)
{
	unsigned long *iptr = (unsigned long*)0;/*pointer equals 0*/
	unsigned long ans = (unsigned long)(iptr + 1);/*add 1 to the pointer*/
	
	fprintf(stdout, "and the answer is->%lu\n", ans);/*whats the answer?*/
	exit(EXIT_SUCCESS);
}

gcc filename.c -Wall -ansi -pedantic -o filename

I was wrong

EDIT:
But now I know why
