How can I get nth element from a list?

How can I access a list by index in Haskell, analog to this C code?

int a[] = { 34, 45, 56 };
return a[1];

I know it's an old post ... but it may be useful for someone ... in a "functional" way ...

import Data.List

safeIndex :: [a] -> Int -> Maybe a
safeIndex xs i 
        | (i> -1) && (length xs > i) = Just (xs!!i)
        | otherwise = Nothing
