C++ program for the Addition of two matrices

In this article, you will learn a C++ program for the addition of two matrices. The matrices are the arrangement of numbers into rows and columns. If we have a matrix having 2 rows and 3 columns. We can say that it’s a 2X3 matrix.

Two matrices are added if both have the same dimensions.

Example: Addition of two matrices in C++

In this program, we will use a multidimensional array to store the elements of matrices and perform addition. After adding their corresponding elements display the result on the console screen.  

//Addition of two matrices in C++
#include <iostream>
using namespace std;

int main()
{
    int i, j,  row, col, firstMatrix[50][50], secMatrix[50][50], result[50][50];

    cout << "Enter number of rows from 0-50: ";
    cin >> row;

    cout << "Enter number of columns from 0-50: ";
    cin >> col;

    cout << endl << "Enter elements of first matrix: " << endl;

    for(i = 0; i < row; ++i)
       for(j = 0; j < col; ++j)
       {
           cout << "Enter element for firstMatrix " << i + 1 << j + 1 << " : ";
           cin >> firstMatrix[i][j];
       }

    cout << endl << "Enter elements of second matrix: " << endl;
    for(i = 0; i < row; ++i)
       for(j = 0; j < col; ++j)
       {
           cout << "Enter element for secMatrix " << i + 1 << j + 1 << " : ";
           cin >> secMatrix[i][j];
       }

    for(i = 0; i < row; ++i)
        for(j = 0; j < col; ++j)
            result[i][j] = firstMatrix[i][j] + secMatrix[i][j];

    cout << endl << "Sum of two matrix will be: " << endl;
    for(i = 0; i < row; ++i)
        for(j = 0; j < col; ++j)
        {
            cout << result[i][j] << "  ";
            if(j == col - 1)
                cout << endl;
        }

    return 0;
}
