Q1. Create a base class named Book. Data fields include title and author; functions include those that can set and display the fields. Derive two classes from the Book class: Fiction, which also contains a numeric grade reading level, and Non Fiction, which contains a variable to hold the number of pages. The functions that set and
display data field values for the subclasses should call the appropriate parent class functions to set and display the common fields, and include specific code pertaining to the new subclass fields. Write a main() function that demonstrates the use of the classes and their functions.
ANSWER
#include <iostream>
#include <string>
using namespace std;
class Book
{
protected:
string title;
string author;
public:
Book(string Title = " ", string Author = " ")
{
title = Title;
author = Author;
}
void setTitle(string newTitle) { title = newTitle; }
void setAuthor(string newAuthor) { author = newAuthor; }
void display()
{
cout << "Title:" << title << endl;
cout << "Author:" << author << endl;
}
};
class Fiction : public Book
{
private:
int level; //Numeric grade reading level
public:
Fiction(string Title, string Author, int Level) : Book(Title, Author) { level = Level; }
void setLevel(int Level) { level = Level; }
void display()
{
Book ::display();
cout << "Numeric grade reading level:" << level << endl;
}
};
class NonFiction : public Book
{
private:
int numbersPages; //Hold the number of pages
public:
NonFiction(string Title, string Author, int number) : Book(Title, Author) { numbersPages = number; }
void setNumber(int Number) { numbersPages = Number; }
void display()
{
Book::display();
cout << "Hold the number of pages:" << numbersPages << endl;
}
};
int main()
{
Book first("Alphabate", "People");
Fiction second("Algebra", "Pythagoras", 3);
NonFiction third("Alice in Wonderland", "Lewis Carroll", 284);
cout << "Firstbook:" << endl;
first.display();
cout << endl;
cout << "Second fictionbook:" << endl;
second.display();
cout << endl;
cout << "Third nonfictionbook:" << endl;
third.display();
return 0;
}
OUTPUT
Firstbook:
Title:Alphabate
Author:People
Second fictionbook:
Title:Algebra
Author:Pythagoras
Numeric grade reading level:2
Third nonfictionbook:
Title:Alice in Wonderland
Author:Lewis Carroll
Hold the number of pages:300
