Question 2
(a) The purpose of the keywords public and private in the class
declaration is to define access levels for the class members.
Public members can be accessed from anywhere, while private
members can only be accessed within the class itself or by friends
of the class.
(b) A class is a blueprint or a template that defines the
properties and behavior of an object. An object, on the other
hand, is an instance of a class, which has its own set of
attributes (data) and methods (functions).
(c) To "instantiate" an object means to create an instance of a
class.
(d) The purpose of a constructor is to initialize objects when
they are created. It is a special member function that is called
when an object is instantiated.
