Actually, your particular point is more for comp.lang.c++, since C
doesn't support pass-by-reference.  Internally, it's all done via
pointers anyway, regardless of the particular language syntax.

There is no functional difference between:

void addp( int *i1, int i2 )
{
    *i1 += i2;
}

and

void addr( int &i1, int i2 )
{
    i1 += i2;
}

They are identical for all intents and purposes, except that in addp(),
the thing i1 points to can be modified.
