Define a derived class , ApartmentBuilding that contains four (4) data members: an integer  named  numFloors, an integer  named  unitsPerFloor, a boolean  named  hasElevator, and a boolean  named  hasCentralAir. There is a constructor  containing parameters  for the initialization  of the above variables  (in the same order as they appear above).

LANGUAGE: C++

CHALLENGE:

Assume  the existence of a Building class . Define a derived class , ApartmentBuilding that contains four (4) data members: an integer  named  numFloors, an integer  named  unitsPerFloor, a boolean  named  hasElevator, and a boolean  named  hasCentralAir. There is a constructor  containing parameters  for the initialization  of the above variables  (in the same order as they appear above). There are also two function: the first, getTotalUnits, accepts no parameters  and returns the total number of units in the building; the second, isLuxuryBuilding accepts no parameters  and returns true  if the building has central air, an elevator and 2 or less units per floor.
