[Haskell-cafe] Haskell - string to list isusses, and more
Hello everyone! Im a Haskell newbie, and Ive have few unanswered questions. For someone more experienced (at least I think so) its a very simple task, but I just cant get a grip on it and its pretty frustrating. It wouldn't be that bad if I haven't browse thru bunch of pages and tutorials and still nothing... The problem is: take a string, and if every words starts with uppercase letter then print yes, else no. Forum Text Bold - yes Frog image File - no Ive had my share of approaches to this, but I just cant make it work. Standard one seemed the most simple: search :: String - String search [] = [] and then use words (splits string on space) to split the string so I could get a list and go through it recursively. But how to apply words to entered string in this form? To find the first letter I came up with: first = take 1 (head x). And compare it with elem or ASCII values to determine if its upper case. Any help, advice or suggestion is appreciated.

Its not great (especially comparing to those one line solutions, wow!), but it works. module Main where startsWithUpper :: String - Bool startsWithUpper []= False startsWithUpper string = if myIsUpper(head(string)) then True else False myIsUpper :: Char - Bool myIsUpper x = if x='A' x = 'Z' then True else False checkAll string = check (words string) check :: [String] - Bool check []=False check x = if all startsWithUpper x then True else False Since importing modules isnt allowed, I made my own isUpper. And thats it, for few days of Haskell, Im happy. Once again, many many thanks to everyone! -- View this message in context: http://www.nabble.com/Haskell---string-to-list-isusses%2C-and-more-tp24022673p24023759.html Sent from the Haskell - Haskell-Cafe mailing list archive at Nabble.com. ___ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
