I was a bit short last time when answering about stl, I'm in a bit of a hurry,
but have more time than I thought I would.
I don't want to use stl because that means I get the overhead that comes with
it. I'd rather not deal with that, or have to work around it.
The program I'm writing is cpu intensive, and the stl adds more overhead than I
want to use for some operations.

Yes, more precisely a const reference. In C++ it's good practice to
make all immutable parameters const references - it avoids the copying
of the variable object (if you omit the & you'll get a local copy of
the variable), and the const forbids you from modifying the original
value.
