Q20. Program to implement Hierarchical Inheritance (Part 1):

Imagine a publishing company that markets books as well as audicassette. Create a class publication that stores the title and price. From this class derive two classes as follows:
– Book, which adds a Pagecount, AuthurName, Edition
– Tape, which adds Playnigtime in minutes, SpeakerName, Date of Recording
Each of these classes should have a getdata( ) and putdat()
Functions to read and to display the data reapectively.

… from College notes (BCA/MCA assignments):

#include <iostream.h>
#include <conio.h>

class CPubs{
	protected:
		char title[20];
		float price;
	};

class CBooks : public CPubs{
	private:
		char aname[20];
		int pcount, edition;
	public:
		void getdata(){
			cout<<"\n Enter Title of Book: ";
			cin>>title;
			cout<<"\n Enter Price: ";
			cin>>price;
			cout<<"\n Enter Author Name: ";
			cin>>aname;
			cout<<"\n Enter Page Count: ";
			cin>>pcount;
			cout<<"\n Enter Edition: ";
			cin>>edition;
			}
		void showdata(){
			cout<<"\n\t Book Title: "<<title;
			cout<<"\n\t Price: "<<price;
			cout<<"\n\t Author Name: "<<aname;
			cout<<"\n\t Page Count: "<<pcount;
			cout<<"\n\t Edition no.: "<<edition;
			}
	};

class CTapes : public CPubs{
	private:
		char sname[20];
		int ptime;
		int dd, mm, yy;
	public:
		void getdata(){
			cout<<"\n Enter Title of Cassette: ";
			cin>>title;
			cout<<"\n Enter Price: ";
			cin>>price;
			cout<<"\n Enter Speaker Name: ";
			cin>>sname;
			cout<<"\n Enter Play Time: ";
			cin>>ptime;
			cout<<"\n Enter Date of Recording (dd mm yy): ";
			cin>>dd>>mm>>yy;
			}
		void showdata(){
			cout<<"\n\t Cassette Title: "<<title;
			cout<<"\n\t Price: "<<price;
			cout<<"\n\t Speaker Name: "<<sname;
			cout<<"\n\t Play Time: "<<ptime;
			cout<<"\n\t Date of Recording: " 
    <<dd<<":"<<mm<<":"<<yy;
			}
	};

void main(){

	CBooks Obook;
	CTapes Otape;

	clrscr();

	cout<<"\n Publishing Company";
	cout<<"\n ~~~~~~~~~~~~~~~~~~";

	cout<<"\n Enter the Information of BOOKS:-"<<endl;
	Obook.getdata();
	cout<<"\n Enter the Information of TAPES:-"<<endl;
	Otape.getdata();

	clrscr();

	cout<<"\n Information of BOOKS & TAPES : -";
