2:	How does a class accomplish abstraction, encapsulation, and data hiding?
A2:	A class represents the operations one can perform on a class object with a public interface of class methods; this is abstraction. The class can use private visibility (the default) for data members, meaning that the data can be accessed only through the member functions; this is data hiding.
