Programa para comprobar si dos arrays dadas son idénticas

El siguiente programa verifica si dos arrays cuadradas de tamaño 4*4 son idénticas o no. Para que dos arrays sean iguales, un número de filas y columnas en ambas arrays debe ser igual y los elementos correspondientes también deben ser iguales. 

Implementación:

C++

// C++ Program to check if two
// given matrices are identical
#include <bits/stdc++.h>
#define N 4
using namespace std;
 
// This function returns 1 if A[][] and B[][] are identical
// otherwise returns 0
int areSame(int A[][N], int B[][N])
{
    int i, j;
    for (i = 0; i < N; i++)
        for (j = 0; j < N; j++)
            if (A[i][j] != B[i][j])
                return 0;
    return 1;
}
 
int main()
{
    int A[N][N] = { {1, 1, 1, 1},
                    {2, 2, 2, 2},
                    {3, 3, 3, 3},
                    {4, 4, 4, 4}};
 
    int B[N][N] = { {1, 1, 1, 1},
                    {2, 2, 2, 2},
                    {3, 3, 3, 3},

    else
