Static Data Members

//static data member declaration (class interface)

class class_name {

...

static data_type static_data_member;

...

};

•A static data member's definition must be supplied only once and is usually placed in the class implementation file. A static data member's definition must be preceded by the class name and the scope resolution operator before the static data member's identifier.

//static data member definition (class implementation)

data_type class_name::static_data_member = initial_value;
