   This program contains hardcoded data on a few individual cars.  The
   user can repeatedly look up all cars that fit any given price range.
   The results of each lookup are presented on the screen.

   Tested with:
      Microsoft Visual C++ 6.0
      Microsoft Visual C++ .NET
      g++ under Linux

           and then to print the data on all cars in the array that fit
