   Purpose: This program reads three numbers a, b, and c through the keyboard
            and  outputs them on the screen in various  FIXED  formats.
            DOUBLE PRECISION IS USED  ( 8 bytes per number )
            
   Algorithm: The main idea here is explained on page 114 of the book
              where the functions: setiosflags, setw, setprecision are
              explained.

              ios:: fixed
              ios:: scientific
              ios:: showpoint

                                                                          */

cout<<" \n\n   Please enter 3 numbers \n  a = ";

// Output everything in fixed point form
