A library maintains a collection of books. Books can be added to and deleted from and checked out and checked in to this collection. Title and author name identify a book. Each book object maintains a count of the number of copies available and the number of copies checked out. The number of copies must always be greater than or equal to zero. If the number of copies for a book goes to zero, it must be deleted from the...
