Imagine a publishing company that does marketing for book and audio cassette versions. Create a class publication that stores the name (string) and price (float) of the publication. Two classes are derived from this class: book, which adds the number of pages (type int), and tape, which adds the playback time in minutes (type float). Write a program that instantiates the Book and Tape classes, allows the user to enter data, and displays the data members.

Imagine a publishing company which does marketing for book and audiocassette versions.

Create a class publication that stores the title (a string) and price (type float) of a publication.

From this class derive two classes: book, which adds a page count (type int), and tape, which

adds a playing time in minutes (type float).

Write a program that instantiates the book and tape classes, allows user to enter data and

displays the data members.

OUTPUT OF THE PROGRAM

#include<iostream>

using namespace std;

class publication

{ 

               char title[10];

               float price;

   

   public:

            void read()

            {

                cout<<"\nEnter Title of the Publication :";

                cin>>title;

                cout<<"\nEnter the price of Publication :";

                cin>>price;

            }

           void show()

            {

                cout<<"Title is :"<<title<<"\n";

                cout<<"Price is :"<<price<<"\n";

            }   

};

class book :public publication 

{

    int page_count;

    

    public :

                void read()

                 {

                     cout<<"\nEnter the page count of Book :";

                     cin>> page_count;

                 }

                 void show()

                 {

                     cout<<"Page count of  Book is :"<< page_count<<"\n";

                 }

};

class tape :public publication

{

    float playing_time;

       

    public :

                void read()

                {

                    cout<<"\nEnter playing time in minutes :";

                    cin>>playing_time;

                }

                void show()

                {

                    cout<<"Playing time in minutes :"<<playing_time<<"\n";

                }

};

int main()

{

    publication *ptr;

    publication  p ;

    p.read();

    p.show();

    

    book b;

    ptr=&b ;

    ptr->read();

    ptr->show();

    

    tape t;

    ptr=&t ;

    ptr->read();

    ptr->show();
