C++ Program for Book-Shop


Problem Statement:

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.

    1. Abhishek Sengar,
      You can make changes to some the variables which you require to have the same values for all the different objects as “static”. Such possible variables are :
      1. Total amount of books bought.
      2. Any new other added functionality.
      Add a new variable “static final_amount” in the class or globally, and update it every time a new book is bought.
      Hope I helped!

      Do revert back, if any further clarification is needed.

      1. ok, would you advise me if you could use any additions here
        for example, is there any design pattern to write to the price file for the book?
        or any other that could be easily added to your program
