C++ Interface ..???

Hi,

What do you mean by interface in C++ ...?
In my knowledge , 2 points are related to the term INTERFACE in c++ ...

1)  Abstract base class --- which we use to do "PROGRAM  TO INTERFACE "
2)  Public functions in a class ---- which is for providing interface to the clients( users of the class )
