$($i$)$ A bookshop uses a personal computer to maintain the inventory books that are being sold at the shop. The list includes details such as author, title, price, publisher, stock position. Whenever a customer wants a book, the shop keeper inputs the title and the author of the book and the system replies whether it is in the list or not. If it is not in the list, an appropriate message is displayed. If book is in the list, then the system displays the book details and asks for number of copies. If the required copies are available, the total cost of the book is displayed; otherwise the message "Required copies not in stock $"$is displayed.
