Question

I was trying to print the address of the pointer variable not the address where it is pointing to, could anyone assist me in achieving that?
Below is what I am trying but it is showing warning which i am not able to resolve.
Thanks!

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

int main()
{
    int* y;
    printf("%p\n",y);
    printf("%x\n",&y);
    y = (int*)malloc(sizeof(int));
    printf("%p\n",y);
    printf("%x\n",&y);
    return 0;
}

Compilation warning:

Warning: format ‘%x’ expects argument of type ‘unsigned int’,
    but argument 2 has type ‘int **’ 

Output:
0xb773fff4
bfa3594c
0x8361008
bfa3594c

Answer 1

Your second printf() should take a "%p\n" format, and strictly a cast:

printf("%p\n", (void *)&y);

The number of machines where the cast actually changes anything is rather limited.
