/*
A book shop maintains the inventory of books that are being sold at shop.
The list includes details such as author,title,price,publisher and stock
position.Whwnever customer wants a book the sale person inputs the title and
author and the system searches the list and display wheather it is available
or not.If it is not appropretae message is displayed.If it is,then system
displays book details and request for no. of copies required.If requested
copies are available,the total cost of requested copies is displayed,
otherwise "requested copies not in stock ." is displayed.Design a system
using class called book with suitable member function and contructor.
Use new operator in construtor to allocate memory. Implement c++ program
for system*/
