20.5 Nested Classes (cont.)

• Does not imply that a List object contains an Iterator object
• The name Iterator is in the scope of the List class
• List member functions can refer to it simply as Iterator
• All other functions refer to it as List::Iterator
• Nested classes need not be public
• Declaring nested class as private encapsulates entire definition
  • May only be created by members of outer class
