Visibility and Inheritance

In most object-oriented programming languages it is possible to control the visibility of data and operations in relation to subclasses

Common visibility distinctions:
- Private
  - Visibility limited to the class itself.
  - Instances of a given class can see each others private data and operations
- Protected
  - Visibility is limited to the class itself and to its subclasses
- Public
  - No visibility limitations
