  5. * Compute average rainfall 
  6. *-------------------------------------------------------------------------------
  7. * This program accepts data and compute the average rainfall over a period of 
  8. * years.
  9. *
  10. * computation is based on the formula:
  11. * Average rainfall per month = total rainfall / (The number of years x 12)
  12. *-------------------------------------------------------------------------------
  13. * INPUT
  14. *    The number of years            : The asked number of years
  15. *    The number of month            : The number of that month
  16. *    Inches of rainfall in the month: The asked inches in that month
  17. * OUTPUT
  18. *    Total inches                    : Total inches of rainfall
  19. *    Average rainfall per month      : The average inches of rainfall per month
