What are iterator design patterns in C++?

What are iterator design patterns in C++?

Iterator design patterns in C++ provide a way to access elements of a collection sequentially without exposing its underlying representation.

Can you explain how to implement an iterator in C++?

Sure! You can implement an iterator by creating a class that defines methods like begin(), end(), and overloads operators like ++ and *.

What are the benefits of using iterators?

Iterators promote code reusability, allow for easy traversal of different data structures, and help in separating the algorithm from the data structure.

Are there different types of iterators?

Yes, there are several types of iterators in C++, including input iterators, output iterators, forward iterators, bidirectional iterators, and random access iterators.
