Question

Answer 1

#include <stdio.h>

int main() {
    int a[4][4];
    int b[4][4];

    for (int i = 0; i < 4; i++){
        for (int j = 0; j < 4; j++) {
            scanf("%d", &a[(i + 1) % 4][j])
        }
    }

    for (int i = 0; i < 4; i++){
        for (int j = 0; j < 4; j++) {
            if (j != 3)
                printf("%d ", a[i][j]);
            else:
            printf("%d\n", a[i][j]);
        }
    }
}
