pointers--when to use them

[exterminator]

No, I mean to say that what can be achieved in C++ with pointer arithmetic cannot be achieved in C++ with references. Clearly Lindley was talking about C++ references, since Java/C# references can be reassigned.

Yeah, alright. Sure. I already accepted it would have been an understatement on my part if I sounded like : nullability was the only different between C++ pointers and C++ references.
