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

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

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

What about their performance in terms of insertion and deletion?

Insertion and deletion can be slower for std::vector compared to other containers like std::list, especially if it requires resizing.

Are there any scenarios where using std::vector iterators is not recommended?

Yes, if you frequently need to insert or delete elements in the middle of the container, consider using std::list or std::deque.

How do std::vector iterators compare with raw pointers?

std::vector iterators provide safety and convenience, while raw pointers offer more control but less safety.
