C++ Program to Add Two Matrices

For example:

Matrix A:

3 7

2 5

Matrix B:

5 6

1 4

Addition of A and B is:

8 13

3 9

Program

``````#include<iostream>
#include<process.h>

using namespace std;

int main()
{
int A[10][10],B[10][10],c[10][10];
int i,j,m,n,p,q;
cout<<"Enter no. of rows and cloumns of matrix A:";
cin>>m>>n;
cout<<"\nEnter no. of rows and columns of matrix B:";
cin>>p>>q;

if(m==p&&n==q)
else
{
exit(0);
}

cout<<"\nEnter matrix A row wise:";

for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
cin>>A[i][j];
}

cout<<"\nMatrix A:\n";

for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
cout<<A[i][j]<<" ";
cout<<"\n";
}

cout<<"\nEnter Matrix B row wise:";
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
cin>>B[i][j];
}

cout<<"\n\nMatrix B:\n";
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
cout<<B[i][j]<<" ";
cout<<"\n";
}

for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
c[i][j]=A[i][j]+B[i][j];
}

cout<<"\nSum of Matrices A and B:\n";
for(i=0;i<m;i++)
{
for(j=0;j<n;j++)
cout<<c[i][j]<<" ";
cout<<"\n";
}

return 0;
}``````

Output

``````Enter no. of rows and cloumns of matrix A:2
2

Enter no. of rows and columns of matrix B:2
2
Enter matrix A row wise:4 5
3 7

Matrix A:
4 5
3 7

Enter Matrix B row wise:2 1
8 2
Matrix B:
2 1
8 2

Sum of Matrices A and B:
6 6
11 9``````
