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

What are the main differences between std::vector and std::list 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::vector instead of std::list?

Use std::vector when you need fast random access and when the size of the container is known in advance. It's more memory efficient.

Are there any performance implications when using std::list?

Yes, std::list has slower access times due to its linked structure, making it less efficient for random access compared to std::vector.

Can you give an example of when to use each?

Sure! Use std::vector for storing a collection of items where you need to frequently access elements by index. Use std::list for scenarios where you need to frequently insert or remove elements from the middle of the container.
