C++ Program to Add Two Matrices Using Multidimensional Arrays

In this program, the user is asked to enter the elements of the two matrices a and b. Then the elements of these two matrices are added and saved it in third matrix. Finally, the result (third matrix) is printed on the screen.

Source Code

#include<iostream>
using namespace std;
int main()
{
    int a[3][3], b[3][3], c[3][3], i, j;

    cout<<"Enter the first matrix\n";
    for(i=0;i <3; i++)
    {
        for(j=0; j<3; j++)
        {
            cin>> a[i][j];
        }
    }
    cout<<"Enter the second matrix\n";
    for(i=0;i <3; i++)
    {
        for(j=0; j<3; j++)
        {
            cin>> b[i][j];
        }
    }
    cout<<"Addition of matrices A & B is\n";
    for(i=0;i <3; i++)
    {
        for(j=0; j<3; j++)
        {
            c[i][j] = a[i][j] + b[i][j];
            cout<< c[i][j] << " ";
        }
        cout<< "\n";
    }
}

Output

Enter the first matrix
1 2 4
4 2 1
8 6 3
Enter the second matrix
1 7 2
5 3 4
8 6 4
Addition of matrices A & B is
 2  9  6
 9  5  5
16 12  7
