I am trying: import System.IO saveArr = do outh <- openFile test.txt WriteMode hPutStrLn

  • 0

I am trying:

import System.IO
saveArr = do
    outh <- openFile "test.txt" WriteMode
    hPutStrLn outh [1,2,3]
    hClose outh

but it doesn’t works… output:

No instance for (Num Char) arising from the literal `1′

EDIT
OK hPrint works with ints but what about float number in array? [1.0, 2.0, 3.0]?

    hPutStrLn can only print strings. Perhaps you want hPrint?

    hPrint outh [1,2,3]
