Public is used for global access so its scope is not only
within the class but also outside the class. For example
public variables will be visible to all classes and any
class or member function can utilize those variables and
member functions.
Private is used only in the class in which it is defined.
It cannot be accessible by its derived members. So private
variables will be visible only to the class to which they
belong and it will not give access to any other classes.
Public and protected members will become private in derived
class.
Protected is used within the class in which it is defined
and derived members of it can also access it. So protected
variables will be visible only to the class to which they
belong and it gave access to its derived classes also.
