Good Haskell coding style of if/else control block?

Question

I\'m learning Haskell in the hope that it will help me get closer to functional programming. Previously, I\'ve mostly used languages with C-like syntax, like C, Java, and D.

You can use the "case"-construct:

doGuessing num = do
    putStrLn "Enter your guess:"
    guess <- getLine
    case (read guess) of
        g | g < num -> do 
            putStrLn "Too low!"
            doGuessing num
        g | g > num -> do 
            putStrLn "Too high!"
            doGuessing num
        otherwise -> do 
            putStrLn "You Win!"
