feetTolnches that accepts a number of feet as an argument, and returns the number of inches in that many feet. Use the function in a program that prompts the user to enter a number of feet and then displays the number of inches in that many feet.
2.Rainfall Statistics

In Haskell (please excuse syntax highlighting; they dont have it for this language):

Code
  1. -- feetToInches.hs

  2. module Main where

  3.  

  4. feetToInches :: Num a => a -> a

  5. feetToInches = (*12)

  6.  

  7. main :: IO ()

  8. main = do

  9.   feet <- putStr "Enter number of feet to convert: ""Enter rainfall for " ++ (snd . (!!n)) months ++ ": ") >> getLine) [0..11]

  10.   let values = map (read :: String -> Float) inputs

  11.   let f g = snd . g $ zip values [0..]

  12.  

  13.   mapM_ putStrLn ["Total rainfall: ""Mean rainfall: ""Month with highest rainfall: " ++ snd (months !! (f maximum)),

  14.                   "Month with lowest rainfall: " ++ snd (months !! (f minimum))]

  15.   where months = zip [0..] ["January", "February", "March", "April", "May", "June", "July",

  16.                             "August", "September", "October", "November", "December"]
