Re: [Haskell-beginners] Reading input

2008/8/20 Yitzchak Gale :

Here's how you could write your main function:

main = do putStr "Enter a list: " lst <- getLine print $ median $ read lst

Another possibility would be a space delimited number list, easier for your users to remember :

parseWordList :: (Read a) => String -> [a] parseWordList str = map read . unwords $ str

main = do putStrLn "Enter a list of integers : " line <- getLine print . median . parseWordList $ line
