Re: [Haskell-cafe] what did I do wrong

Hi, remember that in Haskell argument application is just a space, not using parenthesis and comma like in some imperative languages. In Java: myFunc (a, b) Is equivalent in Haskell to: myfunc a b so center ((1,2), (3, 4)) is a function applied to only one arguement (a tuple of tuples) On Sat, May 10, 2014 at 2:00 PM, Roelof Wobben wrote:

Hello,

...

I have to find the center of 2 points as a assigment for a course on fpcomplete. This is no homework because I do a self-study.

So I did this:

center (x1,y1) (x2,y2) = ( ((x1+x2)/2),((y1+y2)/2) ) main = print $ center ((1,2), (3, 4))

should be:

center (x1,y1) (x2,y2) = ( ((x1+x2)/2),((y1+y2)/2) ) main = print $ center (1,2) (3, 4)

oke,

as I see you changed the main function but I have to make the center function work not change the main function.
