Question

Develop a C++ Project that Apply the OOP concept of separations between the specifications (Book.h), implementations (Book.cpp) and Client (main.cpp). The Class Book that manages the books should include the attributes: ISBN, category, title, author, price and pageCount. Write getters and setters methods for each attribute. The class should include two different constructors, one with ISBN and one with title and author. Add a method to input a new book details, a method to purchase and calculate total cost, a method equals to check if two books are the same, a method to makeCopy and to getCopy of a book. Your Client file should test all the methods with appropriate data of your choice.
