1. Purpose of writing this articleThis article aims to help some people understand some basic concepts about Windows API, C Runtime Library (CRT), and standard C ++ Library (STL. Many people, even experienced programmers, are vague or even have incorrect ideas about these concepts. If you want to know what they are based on and have no time to understand these concepts, please take some time to read this article.2. Basic ConceptsThe following figure s
