  5.  * COMPUTE AVERAGE RAINFALL IN INCHES
  6.  * _____________________________________________________________________________
  7.  * This program calculates the average amount of rainfall in certain months in
  8.  * inches. 
  9.  *
  10.  * Computation is based on the formula:
  11.  * averageRainfall = (rain1 + rain2 + rain3) / 3.0
  12.  * _____________________________________________________________________________
  13.  * INPUT
  14.  * month1 : name of first month
  15.  * rain1 : amount of rain in first month
  16.  * month2 : name of second month
  17.  * rain2 : amount of rain in second month
  18.  * month3 : name of third month
  19.  * rain3 : amount of rain in third month 
  20.  *
  21.  * OUTPUT
  22.  * averageRainfall : average rainfall in the three months
