Hello, everyone.
I need help for my first code.
I write this code for extracting one sentence from text file.
The code is
-----------------------------------------------------------------------------------------------------------------------
import System
import System.Random
main = do myHeader <- readFile "C:\\Documents and Settings\\myHeader.txt"
putStrLn $ myExtractSentence myHeader
myExtractSentence file = ary !! ranNoInt
where
ranNoInt =<< ranNo -- *mark
ranNo = randomRIO (0, n-1)
n = length ary
ary = lines file
----------------------------------------------------------------------------------------------------------------------
There are two questions.
1) I've got following error message.
Haskell>ghc --make Test01.hs -o Test
[1 of 1] Compiling Main ( Test01.hs, Test01.o )
Test01.hs:10:9: parse error (possibly incorrect indentation)
How can fix it?
2) Is it OK at "*mark" line?
Thank you.
S. CHANG
