hi i am new to c++ programing and was wondering if someone could please tell me how to design such a program for a public library:

# define appropriate user-defined data types (enumerations and/or structs) to model the data of the application.
# read the book data from the book data file and store it in a convenient form.
# read the user data from the user data file and store it in a convenient form.
# allow a book to be issued to a user
# allow a book to be returned by a user
# allow the library staff to search for a book by author, to report #whether it is currently in stock or on loan and to indicate in which area of the library it may be found.

Hey dude, just wanted to let you know that it would be better to give more descriptive subject names. So someone knows what's the problem is about before going in. Happy new year...
