You don't have to fix my code if you don't want to. Solving this assignment originally would be even more helpful, I'll adjust my own work to reflect your solution.

Due at the beginning of class. Hand in hard copy of your code and be prepared to run your program. Develop your program as follows: 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 todays date. When a Publication is checked out, save todays date. When a Publication is checked in, indicate if it is overdue and tell subscriber to pay a fine of 5 cents per day.

Totally lost, this is what I have so far:
