Behavioral Design Patterns in C++ - C++ Iterators - III (More Iterators)

The video tutorial explains the addition of iterators to enhance container usage in C++. It introduces constant iterators, their creation, and how they align with the standard library. The flexibility of the iterator pattern is highlighted, allowing for various traversal algorithms. Advanced features for array iterators, such as reverse traversal and operator overloading, are discussed. The tutorial concludes with the implementation of iterator classes for arrays and lists.

What additional features can be implemented in iterator classes based on the underlying data structure?

Explain how overloading the arrow operator enhances iterator functionality.
