House Class
This class inherits the instance variables and methods from Residence, so make sure you do the following:
class House : public Residence {
};
Since this is a subclass of Residence, you can call the constructors from Residence in your initilization list. The House constructor should call it's parents constructor with the values 4, 4, and true.
Since House inherits everything from Residence, you don't need to write any new methods at all! House has a PropertyValue() and NumWindows() method just like Residence because it is a type of Residence.
So, when you want to know the property value of a House object h, you would call:
h.PropertyValue();
