This is considered pretty basic stuff but I just started programming and I'm pretty confused on my assignment.

I'm supposed to write a program that is able to save a list of items such as books, CDs, or DVDs. The items that are saved must have attributes associated with them. For example a book has a title, author, publisher, and ISBN.
I'm supposed to create a program that is able to save the database of items to a file on the hard drive and also retrieve it from the hard drive.

The user should be able to

1. Enter items
2. Display a list of the items
3. Save the list to disk
4. Read the list from disk
5. Sort the list
6. Exit the program

I know I should use arrays and structs but I don't where to start.
