C++: Vector vs List

What are the main differences between vectors and lists in C++?

Vectors are dynamic arrays that provide fast access to elements, while lists are doubly linked lists that allow efficient insertions and deletions.

When should I use a vector instead of a list?

Use a vector when you need fast random access and when the size of the data is known in advance. Lists are better for frequent insertions and deletions.

Are there any performance considerations I should be aware of?

Yes, vectors have better cache locality and are generally faster for accessing elements, while lists have overhead due to pointers.

Can you give an example of when to use each?

Sure! Use a vector for storing a collection of items like scores in a game, and a list for managing a playlist where you frequently add or remove songs.
