Single Inheritance
nEven though inheritance hierarchies allow derived classes to inherit members from their base classes, it does not mean that those members will be accessible within a derived class.
nThis is because members within a hierarchy have their own visibility.
nAs we have seen, public members of a base class are visible and fully accessible by classes derived from them. And, data and member functions in the private section are only available to the class in which they are defined. They are not accessible to any other class (with the exception of friends).
