// This is the test program and question description for SYSC 2002 lab #2 version #2 (D2)

// You are to write and submit files "LibraryCard.h" and "LibraryCard.cpp".
// The following code and the sample executable should make it clear as to what methods are required and what they do.
// You must, of course, create the necessary member variables (fields) for your LibraryCard class.

// Note that the final version of the Date class (Date.h and Date.cpp) is provided on the G: drive for reference.
