15) Create a class MAT which is used to represent Matrix. This class contains two dimensional array, rows, columns of that matrix as data member. Perform addition of matrix using MAT objects with operator overloading. (you can use binary addition operator)

Create a class MAT which is used to represent Matrix. This class contains two dimensional array, rows, columns of that matrix as data member. Perform addition of matrix using MAT objects with operator overloading. (you can use binary addition operator)

#include<iostream>

using namespace std;

class MAT

{

        int a[3][3];

    public:

        void accept();

        void display();

        void operator +(MAT x);

};

void MAT::accept()

{

        cout<<"\n Enter MATRIX Element (3 X 3) : \n";

        for(int i=0; i<3; i++)

        {

                for(int j=0; j<3; j++)

                {

                        cout<<" ";

                        cin>>a[i][j];

                }

        }

}

void MAT::display()

{

        for(int i=0; i<3; i++)

        {

                cout<<" ";

                for(int j=0; j<3; j++)

                {

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

                }

                cout<<"\n";

        }

}

void MAT::operator +(MAT x)

{

        int mat[3][3];

        for(int i=0; i<3; i++)

        {

                for(int j=0; j<3; j++)

                {

                        mat[i][j]=a[i][j]+x.a[i][j];

                }

        }

        cout<<"\n Addition of MATRIX : \n\n";

        for(int i=0; i<3; i++)

        {

                cout<<" ";

                for(int j=0; j<3; j++)

                {

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

                }

                cout<<"\n";

        }

}

int main()

{

        MAT m,n;

        m.accept();       // Accepting Rows

        n.accept();      // Accepting Columns

        cout<<"\n First MATRIX : \n\n";

        m.display();   // Displaying First MAT

        cout<<"\n Second MATRIX : \n\n";

        n.display(); // Displaying Second MAT

        m+n;        // Addition of Two Matrices. Overloaded '+' Operator

        return 0;

}

Output:

Enter MATRIX Element (3 X 3) : 1 2 3 4 5 6 7 8 9 Enter MATRIX Element (3 X 3) : 10 11 12 13 14 15 16 17 18 First MATRIX : 1 2 3 4 5 6 7 8 9 Second MATRIX : 10 11 12 13 14 15 16 17 18 Addition of MATRIX : 11 13 15 17 19 21 23 25 27
