What are some alternatives to std::deque in C++11?

In C++11, alternatives to std::deque include std::vector, std::list, and std::array. Each has its own use cases.

Can you explain when to use std::vector instead of std::deque?

Use std::vector when you need fast random access and don't require frequent insertions or deletions at both ends.

What about std::list? When should I choose that?

std::list is ideal for scenarios where you need frequent insertions and deletions from anywhere in the container, but it has slower access times.

Are there any performance considerations I should be aware of?

Yes, std::vector has better cache performance due to contiguous memory, while std::list has overhead from node pointers.
