Polymorphism With a List of Interfaces

The interface IAnimal declares string Speak(). Complete Cat so it returns Meow and Dog so it returns Woof. The tester puts both in a List<IAnimal> and prints each animal's sound. Do NOT write a Main method.

For a list holding a Cat then a Dog the program prints the output shown in Expected Output.

Expected Output:

Meow↵
Woof↵

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