Suppose that class template Employee has a static data member count. Suppose that three class-template specializations are instantiated from the class template. How many copies of the static data member will exist? How will the use of each be constrained (if at all)?

What will be an ideal response?

Each class-template specialization instantiated from a class template has its own copy of each static data member of the class template; all objects of that specialization share that one static data member. In addition, as with static data members of nontemplate classes, static data members of class-template specializations must be initialized at file scope.
