/*
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.
