Slip 6 - B) Create a C++ class class Matrix { int **p; intr, ¢; public: // member functions }; Write necessary member functions to: i. Accept Matrix elements ii. Display Matrix elements. iii, Calculate transpose of a Matrix. (Use constructor and destructor).

 Solution:

#include<iostream>

#include<conio.h>

using namespace std;

class matrix

{

    int **a,i,j,r,c;

public:

    matrix()           // Dynamic Constructor

    {

cout<<"Enter Row and Coloum of Matrix :\n";

cin>>r>>c;

a=new int*[r];

for(i=0; i<r; i++)

    {

    a[i]=new int[c];

    }

     }

     void accept()

     {

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

for(i=0; i<r; i++)

{

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

    {

cin>>a[i][j];

    }

}

    }

    void display()

     {

cout<<"Elements of matrix are:\n";

for(i=0; i<r; i++)

{

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

    {

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

    }

    cout<<endl;

}

    }

    void transpose()

    {

cout<<"Transpose of Matrix is :\n";

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

{

for(j=0;j<r;j++)

{

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

}

cout<<endl;

}

    }

};

int main()

{

matrix obj1;

obj1.accept();

obj1.display();

obj1.transpose();

}
