Question

in C#

Look at Figures 9-35 and 9-36 on page 392 of your book. There should be two blocks of code: A Book class and an AddBooks program.

In your IDE, create a new .cs file called books.cs, then type this code (you can type both parts in books.cs), then compile it and run it.

 

NOTE: There IS an error with the code 

class Book { } public Book (string title, int pages, double price) { Title = title; NumPages pages; Price = price; } public static Book operator+(Book first, Book second) const double EXTRA = 10.00; string newTitle = first. Title + " and " + second. Title; int newPages = first. NumPages + second. NumPages; double newPrice; if(first.Price > second. Price) newPrice = first.Price + EXTRA; else newPrice = second. Price + EXTRA; return(new Book (newTitle, newPages, newPrice)); } public string Title {get; set;} public int NumPages {get; set;} public double Price {get; set;}
