C++ Program to add two matrix

Program

#include <iostream>
using namespace std;
int main()
{
    int a[10][10], b[10][10], c[10][10];
    int m, n, i, j;
    cout << "Enter the number of rows and columns of a matrix" << endl;
    cin >> m >> n;
    cout << "Enter " << (m * n) << " elements for matrix 1:" << endl;
    for (i = 0; i < m; i++)
        for (j = 0; j < n; j++)
            cin >> a[i][j];
    cout << "Enter " << (m * n) << " elements for matrix 2:" << endl;
    for (i = 0; i < m; i++)
        for (j = 0; j < n; j++)
            cin >> b[i][j];
    for (i = 0; i < m; i++)
        for (j = 0; j < n; j++)
            c[i][j] = a[i][j] + b[i][j];
    cout << "Sum of matrix is:" << endl;
    for (i = 0; i < m; i++)
    {
        for (j = 0; j < n; j++)
        {
            cout << c[i][j] << "\t";
        }
        cout << endl;
    }
}

Output

Enter the number of rows and columns of a matrix
3
3
Enter 9 elements for matrix 1:
56
32
12
98
47
27

57
Enter 9 elements for matrix 2:
16
90
78
87
45
20
