  6. // This program stores weather data for 12 months using
  7. // a structure. For each month, the user enters the total
  8. // rainfall, the high temperature, and the low temperature.
  9. // The program calculates the average monthly rainfall,
  10. // total yearly rainfall, highest temperature and the month
  11. // it occurred, lowest temperature and the month it occurred,
  12. // and the average temperature for the entire year.
  13. //
  14. // ----------------------------------------------
  15. // INPUT
  16. //      For each of the 12 months:
  17. //          total rainfall
  18. //          high temperature
  19. //          low temperature
  20. //
  21. // PROCESSING
  22. //      Validate input (rain >= 0, temp between -100 and 140)
  23. //      Compute total rainfall
  24. //      Compute average monthly rainfall
  25. //      Identify highest and lowest temperature + month
  26. //      Compute average of (high + low)/2 for each month
  27. //
  28. // OUTPUT
  29. //      Total rainfall for the year
  30. //      Average rainfall
  31. //      Highest temperature and month
  32. //      Lowest temperature and month
  33. //      Average yearly temperature
