  5.  * This program asks the user to enter the number of books purchased this
  6.  * month. It then uses an if/else if structure to determine the number of 
  7.  * points awarded based on the following chart:
  8.  *
  9.  *   0 books  -> 0 points
  10.  *   1 book   -> 5 points
  11.  *   2 books  -> 15 points
  12.  *   3 books  -> 30 points
  13.  *   4+ books -> 60 points
  14.  * ------------------------------------------------------------------------
  15.  * INPUT
  16.  *   books : The number of books purchased
  17.  *
  18.  * OUTPUT
  19.  *   The number of points awarded
