How to keep a list of instances of a class?

Question

I'm writing a raytracer in C++ and need to be able to check intersections with every object in a scene (optimizations will come later), and to do this, I need to keep a running list of class instances. A list of pointers, updated when a new instance is created, won't work because as far as I know there is no way to increase the size of the array after it is initialized. I'd really like a built-in (to C++) solution if there is one.

There are any number of STL Containers you could use.
