Abstraction Practice

In this task you are given a code you might already be familiar with since we looked at similar code in multiple previous chapters. It contains an overridden method called MakeSound.

Your task is to convert the Animal class into an abstract class and the MakeSound method into an abstract method.

There should be no change in the output of the program after this modification.
