Derived-Class Member-Function Calls via Base-Class Pointers

• Handle (pointer/reference)
  • Base-pointer can aim at derived-object; but can only call base-class functions
  • Calling derived-class functions is a compiler error; functions not defined in base-class
• Common theme
  • Data type of pointer/reference determines functions it can call
