  4. * CALCULATE RAINFALL STATISTICS
  5. * ______________________________________________________________________________
  6. * This program accepts a double value for the total rainfall for each of 12 
  7. * months and stores the value in an array of doubles. It calculates and displays
  8. * the total rainfall, average monthly rainfall, and months with the highest
  9. * and lowest rainfall.
  10. * ______________________________________________________________________________
  11. * INPUT
  12. * Rainfall				// Rainfall amount for each month
  13. * 
  14. * OUTPUT
  15. * Total rainfall		// Total rainfall for the year
  16. * Average rainfall		// Average monthly rainfall
  17. * Highest month			// Month with the highest rainfall
  18. * Lowest month			// Month with the lowest rainfall
