Making the delegate

Enter using System as usual at the very top of the file. Next, to make a delegate, enter the following:

delegate double CompareValues(double x, double y);

In this line, you have a delegate class. It returns a double and accepts two double data types. So, it encapsulates functions that have that kind of signature.

In the next stage, you'll enter the following within curly braces:

public partial class_Default: System.Web.UI.Page

This line inherits from Page as usual.
