Focus will be on a class. It will have many data members and methods. This class will use a template type say T. The data members and methods will also use template type T. When using this class, only in the main program, we will define what we mean by T. For example, we may define template based class LIST as

     template <class T>      class LIST  {…}

We will declare object mylist as

    LIST <int> mylist;

This tells the computer that mylist is a LIST such that T is “int”.
