nHiding applies the same for data members as it does for member functions.
nAny base class data members that are public or protected are accessible by the derived class.
nIf the derived class
defines data members of the same name
(even though the types may be different), any base class data members of that name are hidden.
nIt is the derived class
data member that is accessed and not
the hidden base class member regardless of the data type.
