Hello to all, i wonder can a IO() function return tuple because i would like to get these out of this function as input for another function.
investinput :: IO()->([Char], Int)
investinput = do
putStrLn "Enter Username : "
username <- getLine
putStrLn "Enter Invest Amount : "
tempamount <- getLIne
let amount = show tempamount
return (username, amount)
Please help.
Thanks.
