//  useStr.cpp - how do I use a "user defined type"?
//
//  step #1 - include header file for user defined type, str.h
//  step #2 - make implementation file, str.cpp and header file, str.h
//            part of your project
//  step #3 - use the member functions of the user defined
//            class to help with the processing in your
//            "executive" file, useStr.cpp.
//
// Note: This application uses just a few of the STR class features.
//       Its purpose is to show how an ADT is used, not to provide
//       exhaustive testing.
