C++ Q\': • The main program and each class definition must be in separate files.

Question

C++ Q':

• The main program and each class definition must be in separate files.
• Hard code test data in the program. Do not enter test data when you run the program.
• Use functions to break your main program into components
• Do not use data structures

Part 1

a) Person class
Write a Person class that tracks subscribers to a library, with these member attributes:
• full name
• identifier (numeric)
• email address
Person has these member functions:
• Constructor - initializes new object
• get and set function for each attribute
Write a main program with these capabilities:
• Create test data for four people
• Display all people
• Edit attributes of an existing person

1b) Book Class
Write a Book class that tracks all books in a library, with these member attributes:
• title
• author
• status - indicates if book is checked out
• borrower – a pointer to the person that has currently checked out book, if any
Book has these member functions:
• Constructor - initializes new object
• get and set function for each attribute
• checkOut - enables Person to check out Book - do not allow if book is already checked
out
• checkIn - enables Person to check in Book
Extend your main program of part 1 with these capabilities:
• Create test data for six books
• display all books in library, along with name of borrower (if any)
• enable people to check books in and out

Part 2

a) Publication Class
In your solution to part 1, rename Book to Publication wherever it appears. Test your
program to ensure it works properly.

2b) 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
All three classes should have constructors, get, and set functions.
Extend your main program to edit and display Publication and Person data. Your user interface
should use menus. For example, the main menu might look like this:
1) Display people
2) Display publications
3) Edit people
4) Edit publications
5) Quit

Given code for part 1. Please post part 2 as a separate question. Thanks.
