What are some tips for using C++11 standard containers?

When using C++11 standard containers, consider using std::vector for dynamic arrays, std::map for key-value pairs, and std::unordered_map for faster lookups.

Can you explain the difference between std::vector and std::list?

Sure! std::vector provides fast random access and is better for cache performance, while std::list allows for efficient insertions and deletions.

What about std::unordered_set? When should I use it?

Use std::unordered_set when you need a collection of unique elements and require fast average-time complexity for insertions and lookups.

Are there any performance considerations I should keep in mind?

Yes, be mindful of the container's memory overhead and the cost of resizing. For example, std::vector may need to reallocate memory when it grows.
