Chapter 9,Problem 1:OOP by Robert Lafore

Problem Statement:

Imagine a publishing company that markets both book and audiocassette versions of its
works. 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). Each of these three
classes should have a getdata() function to get its data from the user at the keyboard,
and a putdata() function to display its data.
Write a main() program to test the book and tape classes by creating instances of them,
asking the user to fill in data with getdata(), and then displaying the data with putdata().

Solution:

//Ahmad Furqan

//P9.1

#include <iostream>

#include <string>

#include <conio.h>

using namespace std;

class publication

{

private:

string title;

float price;

public:

void getdata(void)

{

string t;

float p;

cout << "Enter title of publication: ";

cin >> t;

cout << "Enter price of publication: ";

cin >> p;

title = t;

price = p;

}

void putdata(void)

{

cout << "Publication title: " << title << endl;

cout << "Publication price: " << price<<endl;

}

};

class book :public publication

{

private:

int pagecount;

public:

void getdata(void)

{

publication::getdata(); //call publication class function to get data

cout << "Enter Book Page Count: "; //Acquire book data from user

cin >> pagecount;

}

void putdata(void)

{

publication::putdata();  //Show Publication data

cout << "Book page count: " << pagecount << endl; //Show book data

}

};

class tape :public publication

{

private:

float ptime;

public:

void getdata(void)

{

publication::getdata();

cout << "Enter tap's playing time: ";

cin >> ptime;

}

void putdata(void)

{

publication::putdata();

cout << "Tap's playing time: " << ptime << endl;

}

};

void main(void)

{

book b;

tape t;

b.getdata();

t.getdata();

b.putdata();

t.putdata();

_getch();

}
