Librarian's Assistant Program Help

[Ric]

Hi, I need some help with a program.

The software needs to build the software to manage the library, its books, and library card holders.

This project needs to incorporate two main objects, books and cards:

•Book - this class defines the data that makes up a book object and the actions a book object can take. The data consists of:
o A title of the book
o Author
o Book number
o Whether it’s checked out or not
o Who has the book (Card ID of the holder, 0 if checked in)

A book needs to be able to create itself (constructor), check the status, change the status when a book is checked out/in, check who has the book, and change who has the book


•Card - this class defines the data that makes up a library card object and the actions a card object can take. The data consists of:
o Card holder’s name
o Card holder’s phone number
o Card ID number
o The book number of the book checked out (0 if none)

A card needs to be able to create itself (constructor), check any of the variables of the class, and change the book number.

The program needs to have a recurring main menu that reappears after every menu action is completed and must contain the following options.

1.Show all library cards
2.Show all books
3.Check out a book
4.Check in a book
5.Exit the system

I will post my code in subsequent posts below. Any additional tips would be appreciated. Thanks in advance if you can help!
