How do I create custom iterators in C++?

To create a custom iterator in C++, you need to define a class that implements the iterator interface, including methods like begin(), end(), operator++(), and operator*().

Can you give me an example of a custom iterator?

Sure! Here's a simple example of a custom iterator for a dynamic array class. It includes the necessary methods to iterate through the elements.

What methods should I implement in my iterator class?

You should implement at least operator++, operator*, and operator!= to allow for proper iteration.

Are there any best practices for writing iterators?

Yes, ensure your iterator is lightweight, follow the standard iterator conventions, and provide clear documentation.
