C++ Standard Template Library in Practice - Iterators

The video tutorial covers iterators in the C++ Standard Template Library (STL), explaining their types, traits, and importance in algorithms. It discusses iterator categories, including input, output, forward, bidirectional, random access, and continuous iterators. The tutorial also touches on changes in C++20 and provides a code example to demonstrate accessing iterator traits.

What are iterator traits and why are they necessary?

How will C20 change the way iterators are defined or used?

Describe the process of accessing the iterator traits of a vector iterator.
