C++ Standard Template Library in Practice - Auxiliary Iterator Functions

The video tutorial introduces auxiliary iterator functions from the Iterator Library, such as next, previous, advance, and distance, which provide a universal interface for different types of iterators and containers. It demonstrates using these functions with both vectors and C-style arrays, highlighting their flexibility and utility in standard algorithms. The tutorial includes a practical code example to illustrate how these functions can be applied to access elements and calculate distances within containers. The video concludes with a summary and a preview of the next topic on iterator adapters.
