23 Containers library [containers]

The headers <array>, <deque>, <forward_list>, <list>, and <vector> define template classes that meet the requirements for sequence containers.

The headers <queue> and <stack> define container adaptors ([container.adaptors]) that also meet the requirements for sequence containers.
