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.
