-+ operator 1

[BorlandDave]

Is -+ a valid operator? I'm editing a program written by someone else and I have never come across this before. Could it be a typo? The instance is as follows:

if(var1 && -+var2){
//...
}

Thanks for any help.

Hmmm. I've never seen that before either. What are var1 and var2?

They are both booleans.

That muddies things a bit, too. I don't think -- or ++ work with booleans. It must be a typo.

Ok, thanks for that. I'll look into it a bit further and see if I can work out what is going on!

-+var2 is the same as -(+var2); they're both unary operators. But what the point of the expression is, I've no idea.

Right, so we're all agreed it must be a typo. I was getting worried for a minute
