My usual advice on collections is:

Use vector.
No, really use vector.
Are you sure you shouldn't use vector?

It's the right solution for most cases. One of the nice things is of 
course that vector represents an array of objects. Allocated all in a 
single block of contiguous memory.

Without needing pointer or references.

Yes, of course there are cases for using the other collections, but not 
as common in my experience.
