/*
A book shop maintains the inventory of books that are being sold at the shop. The list 
includes details such as author, title, price, publisher and stock position. Whenever a 
customer wants a book, the sales person inputs the title and author and the system 
searches the list and displays whether it is available or not. If it is not, an appropriate 
message is displayed. If it is, then the system displays the book details and requests for 
the number of copies required. If the requested copies book details and requests for the 
number of copies required. If the requested copies are available, the total cost of the 
requested copies is displayed; otherwise the message Required copies not in stock is 
displayed. Design a system using a class called books with suitable member functions and 
Constructors. Use new operator in constructors to allocate memory space required. 
Implement C++ program for the system.
