Explore the world of STL algorithms in this comprehensive conference talk from ACCU 2016. Delve into the design principles behind the Standard Template Library's algorithms, learn how to effectively utilize them, and gain insights on creating your own algorithms that seamlessly integrate with existing ones. Discover the power of iterators, understand various algorithm categories, and master techniques like min, copy, for_each, and functors. Gain practical knowledge on iterator categories, reference copying, and advanced concepts such as stirring and tokenization. By the end of this talk, you'll have a solid foundation in STL algorithms and the skills to implement custom algorithms that align with STL's design philosophy.
