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. Roelof
