main :: IO() do putStr "Hi there! what is your name: " fanName = getLine do putStr "1 = Insert film, 2 = Become a Fan, 3 = The number of fans of a film, 4 = Film released in a year: " input = getLine read input :: Int (if input == 1 then main x = insertFilm [] else if input == 2 then main x = becomeFan [] else if input == 3 then main x = numberOfFans [])
// I thought using the if statement would work, but now I cant think how to gather the needed input for the function they have chosen?
Well, here input is a String. Type of read is read :: (Read a) => String -> a i.e. If a is an instance of the read class, read will be able to produce a value of type a given a String. So you have to do something like x = read input :: Int read input will not destructively convert the type of input to int Alsom I think case x of will be better than if x = 1... --- Ashok `ScriptDevil` Gautham
