Question

#include<stdio.h>

void f(void)
{
    int s = 0;
    s++;
    if(s == 10)
        return;
    f();
    printf("%d ", s);
}
int main(void)
{
    f();
}

what is the output of the programme!??
i m segmentation fault …what is it?

Answer 1

The problem here is that you’re not statically initializing s. So it’ll always start off as 0 every time you call f(), and f() keeps calling itself over and over again but if(s == 10) is never met. The call stack eventually overflows and boom, segmentation fault.
