Language is C++

Please create only 3 files if possible

1) Main cpp 2) Book.h 3) Library.h

for my better understanding

Write a class named Book that has the following data members: - title :: A string that holds the book's title. - name :: A string that holds the name of the book's author - pages :: An int variable that holds the number of pages in the book. Next, you should create a Library class that has Book object as a private attribute. It should also have attributes for the 'subject' and 'shelf number'. The Library class should have a member function, printBookDetails() that prints the details of the book with its location information in the Library. Write a driver program to test the class Library . The program should have the following additional requirements: The Book class should have a constructor to initialize the object and appropriate getter functions to return the data of a Book object. The Library class should have a constructor to initialize its object with appropriate values of its three data members. Use member-list initializers for both the constructors of the classes.

Answer 1

The solution includes a C++ implementation of a Book class with a constructor and getters, and a Library class with a constructor, a Book object, and a method to print book details. The Book and Library classes use member-list initializers. A driver program tests the Library class.

Step-by-step explanation:

Book and Library Classes in C++

To address the task of creating a Book class with members title, name, and pages, you need to provide a constructor along with getter functions. The Library class will encapsulate a Book object as a private attribute and will include subject and shelf number as additional attributes along with a member function printBookDetails() to display the book's details and location in the library.

The Book class can be defined as follows:

class Book {
private:
std::string title;
std::string author;
int pages;
public:
Book(std::string bookTitle, std::string bookAuthor, int bookPages) : title(bookTitle), author(bookAuthor), pages(bookPages) {}
std::string getTitle() const { return title; }
std::string getAuthor() const { return author; }
int getPages() const { return pages; }
};

The Library class could be implemented like this:

class Library {
private:
Book book;
std::string subject;
int shelfNumber;
public:
Library(std::string libSubject, int libShelfNumber, Book libBook) : subject(libSubject), shelfNumber(libShelfNumber), book(libBook) {}
void printBookDetails() const {
std::cout << "Book Details:\\";
std::cout << "Title: " << book.getTitle() << "\\";
std::cout << "Author: " << book.getAuthor() << "\\";
std::cout << "Pages: " << book.getPages() << "\\";
std::cout << "Subject: " << subject << "\\";
std::cout << "Shelf Number: " << shelfNumber << "\\";
}
};

Finally, a driver program to test the Library class could look like this:

int main() {
Book myBook("The Great Gatsby", "F. Scott Fitzgerald", 180);
Library myLibrary("Classic Literature", 42, myBook);
myLibrary.printBookDetails();
return 0;
}
