Default Interface Method

Give the IGreeter interface a default method Greet() that returns the text Hi, <Name>!, built from the interface's own Name property. Person already implements IGreeter by providing Name, and it should NOT define Greet itself — it will inherit the default. The tester calls Greet() through an IGreeter reference. Do NOT write a Main method.

For a Person named Ada the program prints the output shown in Expected Output.

Expected Output:

Hi, Ada!↵

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