Can I use a vector (or any container) of references? Or must I use pointers?

If not, why not?

std::vector<Object&> vector_of_references;

No.

That is one option, yes.


>> If not, why not?

References always need to refer to an existing object. You cannot declare a reference without specifying which object it refers to. So, you cannot have a container of references.

May I ask why you gave a B grade ? That usually means that something was missing in the answer and/or that something is still unclear. If that's the case, then do not hesitate to ask for clarification where needed.
