Add Two Matrix
“Add Two Matrix” is a basic operation which can be applied over two or more matrices. Here, we have given two matrices of dimension N*M and our task is to add the following matrices and store the result in resultant matrix.
CONDITION: The dimensions of the matrices to be added must be same. Otherwise, we cannot add two matrices.
Example:
Number of rows = 3
Number of columns = 3
| 1 | 1 | 1 |
| 2 | 2 | 2 |
| 3 | 3 | 3 |
| 4 | 4 | 4 |
| 5 | 5 | 5 |
| 6 | 6 | 6 |
| 5 | 5 | 5 |
| 7 | 7 | 7 |
| 9 | 9 | 9 |
C++ Program to add two matrix is as follows:
/* Program to add two matrix */
#include<bits/stdc++.h>
using namespace std;
int main()
{
int N,M;
// Scan Dimensions of the matrix
cout<<"Enter Row Size and Column Size of Matrix:\n";
cin>>N>>M;
int matrix1[N][M];
int matrix2[N][M];
int result[N][M];
// Scan Matrix1 Elements
cout<<"Enter the Elements of First Matrix:\n";
for(int i = 0 ; i < N ; i++)
for(int j = 0 ; j < M ; j++)
cin>>matrix1[i][j];
// Scan Matrix2 Elements
cout<<"Enter the Elements of Second Matrix:\n";
for(int i = 0 ; i < N ; i++)
for(int j = 0 ; j < M ; j++)
cin>>matrix2[i][j];
// Adding matrices
for(int i = 0 ; i < N ; i++)
for(int j = 0 ; j < M ; j++)
result[i][j] = matrix1[i][j]+matrix2[i][j];
//Print Resultant matrix
cout<<"The Resultant matrix is:\n";
for(int i = 0 ; i < N ; i++)
{
for(int j = 0 ; j < M ; j++)
{
cout<<result[i][j]<<" ";
}
cout<<endl;
}
}
OUTPUT: Enter Row Size and Column Size of Matrix: 3 3 Enter the Elements of First Matrix: 1 2 3 1 2 3 1 2 3 Enter the Elements of Second Matrix: 1 2 3 1 2 3 1 2 3 The Resultant matrix is: 2 4 6 2 4 6 2 4 6
