Question about a Haskell function with tuples

Question

how can help me getting this main function running, dont know how to do this, i made a small example:

tuple :: String -> (Bool, String)
tuple x = (True, x)

getStr :: String
getStr = "test"

main = do
    putStrLn snd (tuple getStr)
    putStrLn "End"

Answer 1

You're missing parenthesis around the application of snd :

main = do
    putStrLn (snd (tuple getStr))
    putStrLn "End"
