Add Two Matrices using Multi-dimensional Arrays.Today we make a simple C++ Program To add two matrices in C++ Programming, you have to ask to the user to enter the elements of both the matrix, now start adding the two matrix to form a new matrix.

C++ Program to Add Two Matrix Using Multi-dimensional Arrays

#include<iostream>
#include<conio.h>
using namespace std;
main()
{
int m, n, c, d, first[10][10], second[10][10], sum[10][10];

cout << "Enter the Number of Rows and Columns of Matrix:";
cin >> m >> n;
cout << "Enter the First Elements of Matrix:\n";

for ( c = 0 ; c < m ; c++ )
for ( d = 0 ; d < n ; d++ )
cin >> first[c][d];

cout << "Enter the Second elements of matrix:\n";

for ( c = 0 ; c < m ;c++ )
for ( d = 0 ; d < n ; d++ )
cin >> second[c][d];

for ( c = 0 ; c < m ; c++ )
for ( d = 0 ; d < n ; d++ )
sum[c][d] = first[c][d] + second[c][d];

cout << "Sum of Entered matrices:-\n";

for ( c = 0 ; c < m ; c++ )
{
for ( d = 0 ; d < n ; d++ )
cout << sum[c][d] << "\t";

cout << endl;
}

return 0;
}

Output of Program

Enter number of rows (between 1 and 100): 2
Enter number of columns (between 1 and 100): 2

Enter elements of 1st matrix:
Enter element a11: -4
Enter element a12: 5
Enter element a21: 6
Enter element a22: 8

Enter elements of 2nd matrix:
Enter element b11: 3
Enter element b12: -9
Enter element b21: 7
Enter element b22: 2

Sum of two matrix is:
-1   -4
13   10
