I was expecting the below code to give segmentation fault. Since NULL pointer points to nothing, incrementing something that points to nothing is meaningless. But its printing 0,4,8,12,16.

#include<stdio.h>

int main()
{
    int *p ,i=0; 
    p = NULL;
    for(i=0;i<5; i++) {
        printf("%d
",p++);
    }
    return 0;
}

You're not dereferncing p, you're converting it's stored value to an int. If you where doing:

printf("%d
",*p++);

then you'd seg fault.
