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

Add a new Book class, as well as Music and Video classes. All three classes are derived from the Publication class. Add these member variables:

Book class: • pages • format (hardcover, softcover, digital)

Music class: • duration (seconds) • format (MP3, AAV, WAV)

Video class: • resolution (low, high, 4K) • producer

Add constructors, get functions, and set functions as needed.

Part 4 – Overdue Publications Write a Date class with member variables year, month, and day, and member functions as needed. Add an overloaded ‘-‘ operator, which calculates days between two Date objects.

Publications may be checked out for 21 days. In your main program, add a menu option to enter today’s date. When a Publication is checked out, save today’s date. When a Publication is checked in, indicate if it is overdue and tell subscriber to pay a fine of 5 cents per day.
