  Classes have additional capabilities that structures don't have:
  - Inheritance enables one class to inherit the characteristics of another.
  - Type casting enables you to check and interpret the type of a class instance at runtime.
  - Deinitializers enable an instance of a class to free up any resources it has assigned.
  - Reference counting allows more than one reference to a class instance.
-

  Unless you need to use a class for one of these reasons, use a struct.
