More on Uses-cases for Concepts

Explore advanced uses of C++20 concepts to enhance template programming and type safety. Understand how concepts enable overloading and specialization for different iterator categories, improving algorithm efficiency and correctness in your C++20 code.

We'll cover the following...

Overloading

std::advance is an algorithm of the Standard Template Library. It increments a given iterator iter by n elements. Based on the capabilities of the given iterator, a different advanced strategy could be used. For example, a std::forward_list supports an iterator that can only advance in one direction, while a std::list supports a bidirectional iterator, and a std::vector supports a random access iterator.

Consequently, for an iterator provided by a std::forward_list or std::list, a call to ...
