some issues
Author
When reading a tutorial I come across operators etc.
Is there a dsicernable difference between say
const CVector& operator==
and
const CVector &operator==
surely the ampersand has a different meaning depending on what is hooks onto?
can someone clear this up for us? cheers.
I would have thought the ampersand would sit next to operator, but the tutorials I follow have them varied sometimes???
is this a misprint or....
the more common one in the tuts I follow is my first example
cheers
Im just a beginner!!!

It''s both the same.
But the spelling
const CVector& operator ==
should be considered the better one.
The & operator marks a reference. In this case, the operator ==
returns a constant reference to a CVector object. It would not
make sense to bind the & more to the operator keyword as it
really belongs to the return value (CVector).
