What are the differences between C++ STL containers?

C++ STL offers various containers like vector, list, and map. Vectors are dynamic arrays, lists are doubly linked, and maps are associative arrays.

Can you explain when to use a vector over a list?

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

What about performance differences?

Vectors have better cache performance and lower memory overhead, while lists have constant time insertions and deletions but higher memory usage.

Are there any other important STL containers I should know about?

Yes, consider sets for unique elements, queues for FIFO operations, and stacks for LIFO operations. Each has its own use cases.
