  7.  * This program will calculate and display the total rainfall for the year,
  8.  * the average monthly rainfall, and the months with the highest and lowest
  9.  * amounts.
  10.  * 
  11.  * Formula Used:
  12.  * average = totalRainfall / MONTHS
  13.  * ____________________________________________________________________________
  14.  * Input
  15.  *   MONTHS         :Number of months in a year
  16.  *   monthNames     :Array that stores the names of the months
  17.  *   rainfall       :Array that stores the total rainfall for each month
  18.  * Output
  19.  *   totalRainfall  :Sum of rainfall for all 12 months
  20.  *   highest        :Highest monthly rainfall amount entered 
  21.  *   lowest         :Lowest monthly rainfall amount entered 
  22.  *   highestMonth   :Index of the month with the highest rainfall
  23.  *   lowestMonth    :Index of the month with the lowest rainfall
  24.  *   average        :Average monthly rainfall
