What are the different types of iterators in C++11 for lists?

In C++11, there are several types of iterators for lists: forward iterator, bidirectional iterator, and random access iterator.

Can you explain the differences between these iterator types?

Sure! A forward iterator can only move in one direction, while a bidirectional iterator can move both forward and backward. Random access iterators allow direct access to any element.

When would I use a bidirectional iterator over a forward iterator?

You would use a bidirectional iterator when you need to traverse a list in both directions, such as when implementing certain algorithms.

Are there any specific functions associated with these iterators?

Yes, functions like begin(), end(), rbegin(), and rend() are commonly used with these iterators to access elements.
