54. Swap Two Pointers Using Double Pointers

#include <stdio.h>

void swap_pointers(int **ptr1, int **ptr2) 
{
    // Your logic here
    int *temp = *ptr1;
    *ptr1 = *ptr2;
    *ptr2 = temp;
}

int main() 
{
    int a, b;
    scanf("%d %d", &a, &b);

    int *p1 = &a;
    int *p2 = &b;

    swap_pointers(&p1, &p2);

    printf("%d %d", *p1, *p2);

    return 0;
