[Haskell-cafe] Re: Int->[Char] conversion

Hi,

I am working through Hal Daume's tutorial, trying to do the exercises. I can't figure out how to output an integer with putStrLn (or any other way), I think I need an Int -> [Char] conversion but couldn't find it. Specifically, in Exercise 3.10, I have the product of numbers in pp, and would like to do

putStrLn ("Product: " ++ convertnumbertostring(pp))

but I don't know which function does this...

You could try Hoogle <URL: http://haskell.org/hoogle/ >, though entering Int -> [Char] isn't very helpful, if you put in Int -> String, you get 'show' as the second hit, and that's the function you want. -- Jón Fairbairn Jon.Fairbairn@cl.cam.ac.uk
