How do C++ vector iterators perform compared to other containers?

C++ vector iterators are generally very efficient due to their contiguous memory allocation, allowing for fast access.

What about performance in terms of insertion and deletion?

Insertion and deletion can be slower in vectors compared to lists, as they may require shifting elements.

Are there specific scenarios where I should prefer using vector iterators?

Yes, if you need fast random access and your data size is relatively stable, vectors are a great choice.

How do they compare with other STL containers like deque or list?

Vectors are faster for access and iteration, while deques offer better performance for insertions at both ends, and lists excel in frequent insertions and deletions.
