Haskell打印字符串没有换行符

Question

当我使用这段代码时,它会在结果后打印换行符.我怎么不写新行？

import System.IO

main :: IO ()
main  = do
        a <- getLine
        b <- getLine
        let aa = read a :: Int
        let bb = read b :: Int
        let cc = aa + bb
        print cc

Answer 1

print被定义为putStrLn . show,修复是使用putStr . show $ cc.
