Vector Iterators

What Is an Iterator?

An iterator is like a pointer that helps you move through a vector (or any container) one item at a time.

You can think of it like a bookmark in a book. It points to a specific position so you can move from one item to the next without needing to know the exact index number.

In C++, we use iterators a lot when working with vectors.

Even though the syntax might look a little strange at first, it becomes very useful once you get the hang of it.
