Example: Matrix Addition using Multi-dimensional Arrays in C++

// Matrix Addition using Multi-dimensional Arrays
#include <iostream>
using namespace std;

int main() {
    // Step 1: Declare matrix dimensions
    const int ROWS = 3;
    const int COLS = 3;

    // Step 2: Declare two input matrices and one result matrix
    int matrixA[ROWS][COLS] = {
        {1, 2, 3},
        {4, 5, 6},
        {7, 8, 9}
    };

    int matrixB[ROWS][COLS] = {
        {9, 8, 7},
        {6, 5, 4},
        {3, 2, 1}
    };

    int sumMatrix[ROWS][COLS]; // Matrix to store the sum

    // Step 3: Perform matrix addition using nested loops
    cout << "Performing matrix addition..." << endl;
    for (int i = 0; i < ROWS; ++i) {
        for (int j = 0; j < COLS; ++j) {
            sumMatrix[i][j] = matrixA[i][j] + matrixB[i][j];
        }
    }

    // Step 4: Display the resulting sum matrix
    cout << "\nResultant Matrix (A + B):" << endl;
    for (int i = 0; i < ROWS; ++i) {
        for (int j = 0; j < COLS; ++j) {
            cout << sumMatrix[i][j] << "\t";
        }
        cout << endl; // Move to the next line after each row
    }

    return 0;
