C++ Program to Add Two Matrices

#include<iostream>

using namespace std;

int main()

{

        int a[3][3], b[3][3], c[3][3];

        int i, j;

        cout<<"Enter matrix 1 elements :\n";

        for(i=0; i<3; i++)

        {

                for(j=0; j<3; j++)

                {

                        cin>>a[i][j];

                }

        }

        cout<<"Enter matrix 2 elements :\n";

        for(i=0; i<3; i++)

        {

                for(j=0; j<3; j++)

                {

                        cin>>b[i][j];

                }

        }

    for(i=0; i<3; i++)

        {

                for(j=0; j<3; j++)

                {

                        c[i][j]=a[i][j]+b[i][j];

                }

        }

        cout<<"\nSum of matrix 1 and matrix 2 is\n";

        for(i=0; i<3; i++)

        {

                for(j=0; j<3; j++)

                {

                        cout<<c[i][j]<<"\t";

                }

                cout<<"\n";

        }

        return 0;

}

OUTPUT:

Enter matrix 1 elements :

1

1

1

1

1

1

1

1

1

Enter matrix 2 elements :

1

1

1

1

1

1

1

1

1

Sum of matrix 1 and matrix 2 is

2       2       2

2       2       2

2       2       2
