/**

  This program reads the x and y coordinates of a point and determines
  the quadrant that contains the point.  The program displays the x and 
  y coordinates and the quadrant.

  The quadrant is determined as follows:

      Quadrant      X       Y
         1         >= 0    >= 0
         2         < 0     >= 0
         3         < 0     < 0
         4         >= 0    < 0
