What are the advantages of using iterators in programming?

Iterators provide a consistent way to traverse collections without exposing their underlying structure. They enhance code readability and maintainability.

Can you give me an example of how iterators improve code?

Sure! Instead of using index-based loops, you can use iterators to loop through elements directly, making the code cleaner and less error-prone.

Are there any performance benefits to using iterators?

Yes, iterators can improve performance by allowing lazy evaluation, meaning elements are processed one at a time rather than loading the entire collection into memory.

What types of iterators are commonly used?

Common types include simple iterators, reverse iterators, and even custom iterators that can be tailored to specific data structures.

How do iterators compare to other methods of collection traversal?

Iterators are generally more flexible and safer than traditional methods like for-loops, as they abstract away the complexity of the underlying data structure.
