Classes

• Classes = Data Members + Member Functions
• An object is an instantiation of the class.
• Members of a class a guarded by access specifiers -
  1. private - only accessible to members of the same class or friends (default).
  2. protected- accessible from derived classes.
  3. public - accessible anywhere the object is visible.
• Member functions can be explicitly made inline by writing the body inside the class.
  • We generally inline functions that are very simple, for example, getters and setters.

Constructors

• Constructors are used to initialize data members of a class.
• These special functions have the same name as the class.
• Constructors don’t have return types, not even void.
• Constructors are only executed when an object is created.
• Constructors can be overloaded.
• Default constructors take no arguments.
