  4. * COMPUTE AVERAGE RAINFALL
  5. * This program computes the average rainfall for three months. 
  6. *
  7. * This program will use the formula:
  8. * average = (rainfall_month1 + rainfall_month2 + rainfall_month3)/3
  9. *
  10. * Input
  11. * month1 : the name of a month
  12. * month2 : the name of another month
  13. * month3 : the name of a different month
  14. * rainfall_month1 : the amount of rainfall for month1 
  15. * rainfall_month2 : the amount of rainfall for month2
  16. * rainfall_month3 : the amount of rainfall for month3
  17. *
  18. * Output
  19. * average : the average of rainfall_month1, rainfall_month2, and rainfall_month3
  20. *
