Double Pointer

Code

#include <stdio.h>

void reassign_based_on_value(int **pp, int *n2_ptr) {
    // Your logic here
    if(**pp % 2 == 0) printf("%d ", *n2_ptr);
    else printf("%d", **pp);
}

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

    int *p = &n1;

    reassign_based_on_value(&p, &n2);


    return 0;
}
