What are advanced vector iterators in C++?

Advanced vector iterators in C++ allow for more complex operations on vectors, such as reverse iteration and custom traversal.

Can you explain how to use reverse iterators?

Sure! You can use std::vector<int>::reverse_iterator to iterate backwards through a vector. For example, for(auto it = vec.rbegin(); it != vec.rend(); ++it).

What are the benefits of using iterators over traditional indexing?

Iterators provide a more flexible and generic way to traverse containers, allowing for easier code maintenance and compatibility with different container types.

Are there any performance considerations when using iterators?

Yes, while iterators are generally efficient, certain operations may introduce overhead compared to direct indexing, especially in large containers.
