Defining Static Data Members of a Template

Templates can have static data members. A definition for a static data member can appear in a namespace scope enclosing the definition of the class template that contains the static member. For example:

 template class C {public:   static T stat; //declaration};template T C::stat = 5;  //definition

A static data member can be accessed like this:

 void f() {  int n = C::stat;}
