Answer to Question #180536 in C++ for Aman

Question

Create a class called Matrix having the following data members int rows; int cols; int mat[][]. Write a program to implement the following operations (the ones mentioned in comments) on Matrix. The main() function of the above program is as below: int main() { Matrix m1(3,3); // it will initialize rows and cols m1.getdata(); //accept the data in matrix Matrix m2=m1; //copy one matrix contents into another m2.putdata(); // display the contents of matrix Matrix m3; m3.putdata(); }

#include<bits/stdc++.h>
using namespace std;
class Matrix
{
public:
    int rows,col,n;
    int mat[5][5];
    Matrix(int rows,int col)
    {
        int i=0,j=0;
        for(i=0;i<rows;i++)
        {
            for(j=0;j<col;j++)
            {
                mat[i][j]=0;
            }
        }
    }
    void getdata(int rows,int col)
    {
        int i=0,j=0;
        for(i=0;i<rows;i++)
        {
            for(j=0;j<col;j++)
            {
                cin>>mat[i][j];
            }
        }
    }
    void putdata(int rows,int col)
    {
        int i=0,j=0;
        for(i=0;i<rows;i++)
        {
            for(j=0;j<col;j++)
            {
                cout<<mat[i][j]<<" ";

            cout<<"\n";
        }
    }

int main()
{
    Matrix m1(3,3);
    m1.getdata(3,3);
    Matrix m2=m1;
