Question

How to check if two given matrices are identical in C++

Answer 1

#include <iostream>

#define COLS1 3

bool MatricesIdentical(int matrix1[][COLS1], int matrix2[][COLS1], int rows1, int cols1) {
    for (int i = 0; i < rows1; i++) {
        for (int j = 0; j < cols1; j++) {
            if (matrix1[i][j] != matrix2[i][j]) {
                return false;
            }
        }
    }
    return true;
}

int main()
{
    int matrix1[][COLS1] = { {4, 2, 4},
                             {8, 3, 1} };
    int matrix2[][COLS1] = { {4, 2, 4},
                             {8, 3, 1} };


    int rows1 = sizeof(matrix1) / sizeof(matrix1[0]);
    int cols1 = sizeof(matrix1[0]) / sizeof(matrix1[0][0]);

    if (MatricesIdentical(matrix1, matrix2, rows1, cols1)) {
        std::cout << "yes";
    } else {
        std::cout << "no";
    }
}
