C++ Standard Template Library in Practice - Writing Generic Functions for Iterators

The video tutorial explains the importance of iterators in C++ for writing generic functions. It highlights the benefits of using iterators, such as avoiding code duplication and leveraging the efficiency of the STL. The tutorial demonstrates how to implement a custom iterator function called 'copy every other' and compares it with the standard copy function. It also shows how to use different iterators to achieve the same results, emphasizing the flexibility and power of iterators in C++. The video concludes with a preview of creating custom iterators in the next lesson.
