Deniz already answered your negative-argument question.
But which command do you have bound to `C-c C-c'?
(You can use `C-h k' to find out.)
There are various ways to comment and uncomment multiple lines.
One way is to use command `comment-dwim', bound by default to `M-;'.
Jambunathan suggested using this.
"DWIM" means "do what I mean", and the idea is that the command
does different things in different contexts, but what it does is
always the right thing (what you meant) for each context.
FWIW, I find that "DWIM" is often misguided and presumptuous.
It too often really means "do something the command author thought
would be the right thing".
Personally, I prefer to use command `comment-region', which I bind
to `C-M-;'. With a plain prefix argument (i.e., `C-u') it
uncomments the region. It's an old command, simple and dependable.
It's not dwim: it never second-guesses you.
Use `C-h f' to find out more about any given function (e.g., command).
