Using Default Arguments with Constructors

• Constructors
  • Can specify default arguments
  • Default constructors
  • Defaults all arguments
  • OR
  • Explicitly requires no arguments
  • Can be invoked with no arguments
  • Only one per class

The program of Figs. 1.17-1.21 enhances class Time to demonstrate how arguments are implicitly passed to a constructor.
