Back to Basics: Standard Library Containers in C++ - Rainer Grimm - CppCon 2022

From a bird’s-eye view, the Standard Template Library (STL) consists of three components. Those are containers, algorithms that run on the containers, and iterators that connect both of them. The STL has five sequential and eight associative containers. I hear your question:
When should I use a sequence container or an associative one?
When I decided for a sequence container or an associative one, which one should I use?
The answers to these questions depends mainly on two facts: use case and performance.
You may not know it but std::array and std::vector are your best friends for sequence containers, and you are most of the time fine with std::unordered_map when you need an associative container.

Rainer has worked as a software architect, team lead, and instructor since 1999. In 2002, Rainer created a company-intern meeting for further education and had given training courses since 2002. Rainer's first tutorials were about proprietary management software, but he began teaching Python and C++ soon after. In his spare time, he likes to write articles about C++, Python, and Haskell and speak at conferences. Rainer publishes weekly on his English blog Modernes C++. Since 2016, Rainer has been an independent instructor, giving seminars about modern C++ and Python. Due to his profession, he constantly searches for the best way to teach modern C++. He published several books in various languages about modern C++ in the last ten years, including the last one "C++ Core Guidelines Explained: Best Practices for Modern C++".
