54. Swap Two Pointers Using Double Pointers

#include <stdio.h>

void swap_pointers(int **pp1, int **pp2) {
    // Your logic here
    int *temp = *pp1;
    *pp1 = *pp2;
    *pp2 = 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;
}
