A friend and I were working on a Haskell version of
 Towers of Hanoi yesterday, and I tried writing out the
 program today, but got stuck on outputting newlines as
 part of the string; viz:
...
| n == 1 = putStrLn ("Move " ++ show source ++ " to
 " ++ show dest ++ "." ++ show '\n')
show '\n' = "\\n"

"\n" == "\n"

Therefore:
...
| n == 1 = putStrLn ("Move " ++ show source ++ " to
 " ++ show dest ++ "." ++ "\n")
Note that you need the brackets, an in general don't call show on a
String or a Char.

Thanks
