Question
Design a C++ program, the solution Includes all the following parts:
A. The code and the files necessary to compile and test the project.
B. Test Plan: Showing how you tested the program (show the steps of your testing procedure along with screen shots).
C. A short description of the design plan and general comments.
Objective: Write a C++ program to manage a library system. The main user is the librarian.
Building Requirements:
1. The system should load a catalog of books, journals, and magazines at the start of the program. (at least five of each)
2. A user can search the catalog: The user of the system can search the library’s catalog by using the name of the item. Also, a user can list books by category (Book, Journal, or magazine). If you are looking specifically for a book, you can search by the name of the author.
3. A user can check out books, journals, or magazines: The user needs to find the item first, then they can check it out. A user cannot check out an item that is already checked out.
4. A user can return books, journals, or magazines: A user can return an item. The user needs to find the item first, then they can return it.
5. Add new books, journals, or magazines to the catalog. A librarian can add a new item to the catalog.
PS: Each item should have the following data members: ID, Name, and Status. Books have the “Author_name” as an additional data member. Journals have the “Volume” as an additional data member. Magazines have the “Issue_number” as an additional data member.
The program must have the following properties:
- You should do error handling (Ex: A librarian cannot add a book that already exists)
- You should use C++ concepts that we covered in class. Example: (inheritance) You can design a generic library item, then design derived classes for different kinds of items that a user can check out.
- Your program should use a suitable data structure to store the items.
Also, design a menu (should still appear until the exit option is chosen) in the Main program that has the following options implemented to test your classes’ functionality(It's very important!):
1. Search Catalog
2. Check out
3. Return
4. Add a new item
5. Exit
Extra Credit:
- Save and load data from and to a file.
