Question

c++

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 functions: 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.

Define another derived class, a single family house that could be initialized with a constructor as a single story house which is a single cube and two story house which one cube on top of another. Create two objects, one object is a single story house, another object is a two story house.

#include<bits/stdc++.h>
using namespace std;
//base class
class house
{
   string type;
   public:
       house()
       {
       }
};
//derived class ApartmentBuilding
class ApartmentBuilding : public house
{
   //members
   int numFloors,unitsPerFloor;
   bool hasElevator,hasCentralAir;
   public:
       //Constructor
       ApartmentBuilding(int nF,int uF,bool hE,bool hC)
       {
           numFloors=nF;
           unitsPerFloor=uF;
           hasElevator=hE;
           hasCentralAir=hC;
       }
       //member functions
       int getTotalUnits()
       {

       {
           bool temp=hasElevator&&hasCentralAir&&(numFloors<=2);

   singlefamilyhouse sfh1(1),sfh2(2);
   sfh1.show();
   sfh2.show();
  
   return 0;
}
