Static members

A static member is part of a class, but not part of an object of a class, so there's only one instance of them however many objects of that class are created. This is useful if, for instance, you want to keep a count of how many objects are created. A static member function

1.

can access private data

2.

is in scope of class

3.

but can't be invoked on an object - objectname.staticmemberfunction() can't access any object-specific data.
