Yes.

A static member variable isn't part of any particular object
(instance), but is a global variable. Consequently, it has to belong
to a particular object file. This means that you have to define it at
the top level of some source file (as well as declaring it within the
class definition).

If the variable is private, then you can only access it from within a
member function of the class to which it belongs.
