Classes in C++

classes define the structure and its behavior (operations)
similar to structs but default is private with classes
other facilities for object orientation also included in classes (e.g., inheritance…a later topic)
both structs and classes allow you to define encapsulated data and functions

Interface

3 Sections
- public
  - data and operations visible, accessible and useable by all clients
- private
  - data and operations not visible to other classes
- protected
  - visible to subclasses (inheritance)
