Iterator Types

Understanding iterator types is crucial in C++ because they serve as the backbone for traversing data structures efficiently. While the basics of iterators give you a foundational understanding, diving into the different types will allow you to leverage their full potential in real-world applications. When you know which iterator to use in various scenarios, you can write cleaner, more efficient, and more expressive code.

Let’s explore the various iterator types available in C++ and how they can be effectively utilized.
