Double Pointer

Code

#include <stdio.h>

void reassign_based_on_value(int **pp, int *n2_ptr) {

if (**pp % 2 == 0) 
{
        // Value is even → point to n2
        *pp = n2_ptr;
} 
    // else 
    // {
    //     // Value is odd → point to n1
    //     *pp = n1_ptr;
    // }



}

int main() {
    int n1, n2;
    scanf("%d %d", &n1, &n2);

    int *p = &n1; //p1

    reassign_based_on_value(&p, &n2);

    printf("%d", *p);

    return 0;
}
