Default Interface Method

C# interfaces can provide a DEFAULT method body. Add a default method Greet() to IGreeter that returns Hello,  + Name() + !, reusing the Name() each class supplies. The Person class only implements Name(). Do NOT write a Main method.

A default interface method is called through an interface reference. For a Person named Sam the program prints the output shown in Expected Output.

Expected Output:

Hello, Sam!↵

= newline. The output ends with a newline — print one after the last line.
