#include<stdio.h>
int main()

    static int GATE[]={100,200,300,400,500};  
    static int *p[] = {GATE+2, GATE, GATE+3, GATE+4, GATE+1};  
    int **ptr = p;
    ptr++;

Where did you get this question from? This question is stupid. See my answer below for the reason this question is stupid.

Answer 1

In its current form it will not actually print the address of GATE array, because "%d" conversion specifier has been used in the printf statment. %d is used to print integers, not address.

Also C standard doesn't specify what should happen when conversion specifier and argument mismatch, hence running this program may lead to undefined behaviour.

This is from KN King C programming a second approach, 2nd edition.

Hence I commented that this question is stupid.

You are welcome :)

But where did you get this question from?

From gate zeal  sheet

Answer 2

This is printing address of GATE, ie. address of 100.

For actually printing 100, the line should be - printf("%d", **ptr);

So yes, running this program gets address of GATE which looks like a garbage value

Comments

yes if there is **ptr then surely it will print.
I think there is maybe typo.
