Could I have a C# code based off these requirements:

Add $3$ interfaces to your RPG project:

One interface should have a method for being the target of an attack

Another interface should have a method for attacking a target

The last interface will combine the previous $2$ interfaces

Both Hero class and Villain class should implement the third interface

Names of the interfaces are up to you

Naming Convention should start with $$I$$

Naming Convention should be an adjective

Usually ending in $$able$$

The method is typically based on the interfacename:

ICloneable $->$ Clone

IComparable $->$ CompareTo

IDisposable $->$ Dispose
