It
is important to realize that memory is allocated for static
|
|
data
members when we explicitly define those static data
|
|
|
members,
not when we declare the static data members as
|
|
|
part
of a class definition. Think of the static data member
|
|
|
declarations
within a class as external references to data
|
|
|
members
defined elsewhere.
|
|
| • |
Clients
can access a public static data member by saying
|
|
|
class_name::static_data_member
|
|
| • |
It is
also possible for clients to access a public static data
|
|
|
member
once an object is defined for that class by saying
|
|
|
object_name.static_data_member.
