C++11: std::list vs std::deque

What are the main differences between std::list and std::deque in C++11?

std::list is a doubly linked list, while std::deque is a double-ended queue. std::list allows for efficient insertions and deletions, but std::deque provides faster access to elements at both ends.

When should I use std::list over std::deque?

Use std::list when you need frequent insertions and deletions in the middle of the container. std::deque is better for scenarios where you need fast access to both ends.

Are there any performance considerations I should be aware of?

Yes, std::list has a higher memory overhead due to node pointers, while std::deque may have better cache performance due to its contiguous memory allocation.

Can you give an example of when to use each?

Sure! Use std::list for implementing a playlist where you frequently add or remove songs. Use std::deque for a buffer where you need to add or remove elements from both ends efficiently.
