When should I use lists or vectors in C++?

When should I use lists instead of vectors in C++?

You should use lists when you need efficient insertions and deletions from anywhere in the container, as lists allow for constant time complexity for these operations.

What about vectors? When are they a better choice?

Vectors are better when you need fast random access to elements, as they provide constant time complexity for accessing elements by index.

Are there any performance considerations I should be aware of?

Yes, vectors have better cache performance due to their contiguous memory allocation, while lists may have overhead due to node pointers.

Can you give me an example of when to use each?

Sure! Use a vector for a dynamic array of items where you frequently access elements, and a list for a playlist where you often add or remove songs.
