What are the differences between std::list and std::stack in C++?

What are the differences between std::list and std::stack in C++?

std::list is a doubly linked list allowing insertion and deletion from both ends, while std::stack is a container adapter that provides LIFO access.

Can you explain the use cases for each?

Sure! Use std::list when you need frequent insertions/deletions, and std::stack when you need to manage data in a last-in-first-out manner.

Are there performance differences I should be aware of?

Yes, std::list has O(1) complexity for insertions/deletions, while std::stack's performance depends on the underlying container, typically std::deque.

Which one is more memory efficient?

std::list generally uses more memory due to its node overhead, while std::stack's efficiency depends on the underlying container.
