Bookshop inventory system
This is a simple project where the system maintains the inventory of books in a bookshop. If a customer purchases a book, the book's count will decrease; if a book is added, the same is updated. Notice the use of pointers. You can modify the code to add a book ID and make the search based on book ID or make the search using just one parameter giving multiple results, and so on.
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 system.
