C++ Programing

Book Pile Imagine a pile of books on your desk. Each book is so large and heavy that you can remove only the top one from the pile. You cannot remove a book from under another one. Likewise, you can add another book to the pile only by placing it on the top of the pile. You cannot add a book beneath another one.

For this assignment, you will design a class called BookPile that represents the pile of books. The class will simply keep track of the titles of the books on the pile. The pile may contain no more than 10 books at any one time.

Your class should support the following functions as part of its public interface:

An accessor function called get_count. It takes no parameters and returns an int. It returns the number of book currently on the pile

. An accessor function called get_top_title. It takes no parameters and returns a string. It returns the title of the book on the top of the pile. If the pile is empty, it should return a null (empty) string

. A mutator function called add_book. It takes a string as a parameter that represents the title of a book to be added to the pile. It should return a bool to indicate whether or not the book was successfully placed on the pile. Adding a book is unsuccessful when attempting to add a book when the pile is full (i.e. the pile contains 10 books).

A mutator function called remove_book. This is a void function that takes no parameters. It removes the top book from the pile.If the pile is empty, the function should have no effect on the pile.

Build your class as a header and implementation file pair. A test program is provided and attached to this assignment item for your convenience. Your implementation should work without modification to the test program.

When submitting this assignment, include your header and implementation file pair as well as your test program. Submit your source files as TGZ archive prepared using your instructors web site.
