Derived Classes
- The Clock class presented in clocks1.cpp provides a base class that can tell the current local time.
- You can set a clock to either "military" or "am/pm" format.
- We will create a derived class,
TravelClock that gains two additional data fields:
location and time_difference.
- The time for a TravelClock is computed
by taking the local time and adding the time difference.
TravelClock clock("New York", 3); cout << "The time in " << clock.get_location() << " is " << clock.get_hours() << ":" << clock.get_minutes();
