Answer to Question #181061 in C++ for RAMAKRISHNA

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();

}

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++)
