C++: std::list vs std::vector

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

The main differences are in their underlying data structures: std::vector is a dynamic array, while std::list is a doubly linked list.

When should I use std::list instead of std::vector?

Use std::list when you need frequent insertions and deletions from the middle of the container, as it performs better in those scenarios.

Are there any performance considerations I should be aware of?

Yes, std::vector has better cache performance and is generally faster for random access, while std::list has overhead due to pointers.

Can you give an example of when to use each?

Sure! Use std::vector for storing a collection of items where you need fast access, like a list of scores. Use std::list for a playlist where you frequently add or remove songs.
