Static Members
•To specify static member functions, we must declare the functions to be static in the class definition (interface file) using the keyword static .
•Then, define those static member functions in the class implementation file.
•The definition of our static member functions should look identical to the definition of non-static member functions.
•The scope of a static member function is the same as that of a non-static member function.
•Access to a static member function from outside the class is the same as access to a non-static member function and depends on whether the member is declared as public, protected, or private.
