Write a program to design a class representing the information regarding digital library (books, tape: book & tape should be separate classes having the base class as media ). The class should have the functionality for adding new item, issuing, deposit etc. the program should use the runtime polymorphism.

#include<iostream.h>
#include<string.h>
class media
{
protected:
char title[50];
float price;
public:
media(char *s, float a)
{
strcpy(title, s);
price = a;
}
virtual void display(){}
};
class book : public media
{
int pages;
public:
book(char *s, float a, int p) : media(s,a)
{
pages = p;
}
void display();
};
class tape : public media
{
float time;
public:
tape(char * s, float a, float t):media(s,a)
{
time =t;
}
void display();
};
void book ::display()
{
cout<<"\n Title:"<<title;
cout<<"\n Pages:"<<pages;
cout<<"\n Price:"<<price;
}
void tape ::display ()
{
cout<<"\n Title:"<<title;
cout<<"\n Play Time:"<<time<<"mins";
cout<<"\n Price:"<<price;
}
int main()
{
char * title = new char[30];
float price, time;
int pages;
cout<<"\n Enter Book Details \n";
cout<<"\n Title:";
cin>>title;
cout<<"\n Price:";
cin>>price;
cout<<"\n Pages:";
cin>>pages;
book book1(title, price, pages);
cout<<"\n Enter Tape Details";
cout<<"\n Title:";
cin>>title;
cout<<"\n Price:";
cin>>price;
cout<<"\n Play Times(mins):";
cin>>time;
tape tape1(title, price, time);
media* list[2];
list[0] = &book1;
list[1] = &tape1;
cout<<"\n Media Details";
cout<<"\n..............Book.....";
list[0]->display ();
cout<<"\n..............Tape.....";
list[1]->display ();
return 0;
}
