   // The following not OK, but are just the default values:
   typedef ostream_iterator<int>::char_type CHT1;
   typedef ostream_iterator<int>::traits_type CHTR1;

   // ostream_iterator for stream cout
   // with new line delimiter:
    ostream_iterator<int, CHT1, CHTR1> intOut ( cout , "\n" );

   // Standard iterator interface for writing
   // elements to the output stream:
   cout << "The integers written to output stream\n"
        << "by intOut are:" << endl;
   *intOut = 1;
   *intOut = 10;
   *intOut = 100;
