I sometimes like to use unary plus purely for aesthetic reasons. That is, the following: coordinates.push_back(new Vector(-w,-h)); coordinates.push_back(new Vector(+w,-h)); coordinates.push_back(new Vector(+w,+h)); coordinates.push_back(new Vector(-w,+h)); ..looks nicer to me than: coordinates.push_back(new Vector(-w,-h)); coordinates.push_back(new Vector(w,-h)); coordinates.push_back(new Vector(w,h)); coordinates.push_back(new Vector(-w,h)); Of course, I could (should?) always use whitespace...

Um, because that operator is used for i + j and returns the sum, right? Did I miss something? I suspect you (Robert) might be looking at the unary + operator... Doh! So I was. I didn't even look at the argument list when I saw it because I've never overloaded the unary +! I don't know anyone who does, but I assume that someone out there, someone will, and would be irritated if it didn't work the same as the built in integer types. that person is me definitly
I was just wishing, when I wrote that, that I did know someone who did that... purely out of curiosity, I wanted to ask why they (i.e. you) did that? Is it just to make it more obvious that it's supposed to be a positive number instead of a negative one? - -- Chad Nelson Oak Circle Software, Inc. * * * -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/
