Question

1. Two 2-D arrays A [ ] [ ] and B [ ] [ ] are of type boolean and represent two black and white images ( 1’s (black) and 0’s (white) ) having the same size (n x m).

Implement a Boolean function to receive these two images(arrays) as an input and return true if A is the negative of B (i.e. each pixel of A is the complement of the corresponding pixel of B) and false otherwise.

CODE:

#include <bits/stdc++.h>
#define SIZE 100
using namespace std;
bool check(int m, int n, int a[][SIZE], int b[][SIZE])
{
    for (int i = 0; i < m; i++)
        for (int j = 0; j < n; j++)
            if (a[i][j] == b[i][j]) // if the pixel is same return false
                return false;
    return true;
}
int main()
{
    int m, n;
    cout << "\nEnter the dimensions: ";
    cin >> m >> n;
    int a[SIZE][SIZE], b[SIZE][SIZE];
    cout << "\nEnter array A:\n"; // Input array A
    for (int i = 0; i < m; i++)
        for (int j = 0; j < n; j++)
            cin >> a[i][j];
    cout << "\nEnter array B:\n"; // Input array B
    for (int i = 0; i < m; i++)
        for (int j = 0; j < n; j++)
            cin >> b[i][j];

    if (check(m, n, a, b)) // check function called
        cout << "\nTrue\n";
    else
        cout << "\nFalse\n";
    return 0;
