I would like to ask about data structures (stacks and queues) from both a competition programming perspective and a practical perspective.
I assume that stacks and queues are included in the standard library, but do you ever extend these classes yourself?

What I have tried:

Would like to hear from different people.

Then this is not really the right forum for a discussion. Try posting on the C++ discussion board instead C / C++ / MFC Discussion Boards[^]

Stacks and Queues are specific structures that dont; really get "Extended" because they are generic already - they hold any type of data and provide the mechanisms to manipulate that data within the structure itself: push, pop, and peek for stacks, enqueue and dequeue for queues (along with the usual size related stuff). Extending that isn't normally necessary because what you would end up with isn;t a stack or queue! Certainly, I've never needed to extend a stack or queue, and I've been doing this stuff for over 40 years ... well before classes or generics even existed.

Instead, they get embedded into other classes which wrap them in a layer of data abstraction to hide the storage mechanism from "higher classes".
