// Assignment11.cpp : Defines the entry point for the console application. //

#include "stdafx.h"

#include <iostream> #include <string> using namespace std; int main() {

int size, m, n, c, d, first[10][10], second[10][10], sum[10][10];

system ("pause");

return 0; }

In this assignment, I don't want you to change any functionality. The solution for assignment 11 was not very object-oriented. For this assignment, I want you to design a class to perform all of the operations that we did in assignment 11.

Thus, you will create a class called Matrix and then design the class to use the attributes from assignment 11 and then create methods to support them. Keep all of the code in a single .cpp file.

PROGRAM:

#include<iostream>

using namespace std;

class Matrix

{

private:

int first[10][10], second[10][10], sum[10][10]; //define matrices first, second, sum

int size, m, n;

int c, d;

public:

void initMatrix();

void sumOfMatrices();

void printMatrix();

};

void Matrix::initMatrix()

{

cout<< "Enter the number of rows and columns of matrices: ";

cin >> size;

m = size;

n = size;

cout << "Enter the elements of first matrix: ";

for( c = 0 ; c < m ; c++ )

for( d = 0 ; d < n ; d++ )

cin >> first[c][d];

cout << "Enter the elements of second matrix: ";

for( c = 0 ; c < m ; c++ )

for( d = 0 ; d < n ; d++ )

cin >>second[c][d];

}

void Matrix::sumOfMatrices() //finding sum of the matrices

{

for( c = 0 ; c < m ; c++ )

for( d = 0 ; d < n ; d++ )

sum[c][d] = first[c][d] + second[c][d];

}

void Matrix::printMatrix()

{

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;

}

}

int main()

{

Matrix M1; //create new object

M1.initMatrix(); //calling method initMatrix()

M1.sumOfMatrices(); //calling method sumOfMatrices()

M1.printMatrix(); // calling method printMatrix()

}

Output :
