Plz... Somebody explain me this...

Question

What is the output of this code?

#include <stdio.h>
int main() {
static int a[]={ 10,20,30,40,50 };
static int *p[] = {a, a+3, a+4, a+1, a+2};
int **ptr = p;
ptr++;
printf("%d%d", ptr - p, **ptr);
}

Answer 1

**ptr has p or a
**ptr++ has p+1 i.e.1 indexed element of p i.e. a+3 i.e. 3 index element of a i.e. 40
**ptr-p is actually p++ - p i.e. 1

So output: 1 40
