Question

C++ Program

Develop your program as follows:

• Use the Library Lab as the starting point for this homework. • Complete each part before you begin the next. • The main program and each class definition must be in separate files. • Ensure your code conforms to your Style Guide.

Part 1 – Copies of Books

The library has multiple copies of each book. Track the number of copies of each book, and track one borrower for each copy. Do not allow book check out if all copies are already checked out.

Part 2 – Publication Class

In your Library Lab, rename Book to Publication wherever it appears. Test your program to ensure it works properly.

Part 3 – Book, Music, and Video classes
