What is the basic difference between public class and class?

How are the members of a class public or private?

The public members of a class can be accessed from anywhere in the program using the direct member access operator (.) with the object of that class. In the above program, the data member radius is public so we are allowed to access it outside the class. The class members declared as private can be accessed only by the functions inside the class.

What’s the difference between public and private access?
