Most people would suggest you pass pointers.  This makes the code easily
understandable and it's obvious what's being potentially modified and
what's not.

References in C++ were added to facilitate operator overloading, and
became a standard part of the language.  But under normal circumstances
they should be used exceptionally sparingly (except when passing const
references).
