The containers and functions inside the C++ Standard Library are defined in the std namespace. WebThe standard library doesn't directly support that technique, but the two can be made to coexist. ” “ In a future revision of C++, it might make sense to relax the restriction on instantiating standard library templates with incomplete types.

The container is a container of handle objects (by value or by pointer, your choice; by value is easier). Each handle object knows how to “hold on to” (i.e., maintain a pointer to) one of the objects you want to put in the container.
