What are the best practices for using iterators in programming?

Some best practices include using iterators to avoid memory overhead, ensuring they are easy to use, and keeping them simple.

Can you explain why avoiding memory overhead is important?

Avoiding memory overhead is crucial because it helps improve performance and reduces the risk of memory leaks.

What are some common mistakes to avoid when implementing iterators?

Common mistakes include not handling edge cases, failing to reset the iterator, and not providing clear documentation.

How can I test my iterators effectively?

You can test iterators by using unit tests to check their behavior with various input scenarios and edge cases.
