You've already got a good answer explaining what you need to know.

I just wanted to add that for about the last ten years there have been very few occasions when you need to put the '&' on the front of a function call. Unless you know that you need it (and in 99% of cases - including this one - you don't) then you should leave it off.

And if you got that bad habit from a book or an online tutorial then you should view any other information that you got from the same place with deep suspicion.
