Here's what I came up with. I especially like the 2nd version, even
though it's longer, as it seems very declarative.
caps1 s = all (\x -> isUpper (head x)) (words s)
caps2 s = all startsWithUpper (words s) where
startsWithUpper w = isUpper (head w)
I'm also fairly new to Haskell, so I would appreciate feedback from
the more experienced.
Thanks.

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.
Thanks in advance!
