- Static member functions are used to maintain a single copy of a class member function across various objects of the class. Static member functions can be called either by itself, independent of any object, by using class name and :: (scope resolution operator) or in connection with an object.

2. Static member functions do not have this pointer.
3. Static member function can not be virtual.
