Class functions (cont'd from previous slide)

Class functions can be declared public, private, or protected. 

Public class functions can be accessed by any code in any function that knows the name of the function and the name of the class in which the function is defined.

Public class functions can be accessed in the total absence of an object of the class.

Access to private class functions and protected class functions is somewhat more restricted.  I will defer discussion of such functions until a more advanced course.
