Can You Access and Iterate Over the Underlying Deque of a `std::queue`?

Accessing Underlying Data Structure in std::queue

Iterating through a std::queue can be a confusing task. By default, the queue utilizes the deque as its underlying data structure. This raises the question of whether it's possible to access and iterate over the deque.

The answer, however, is no. Standard container adapters like std::queue provide a limited interface that excludes iteration functionality. If iteration is desired, the deque should be used directly, eliminating the need for the adapter.
