Unlike regular function calls, both avoid the overhead of subroutine push/pop operations at runtime, which can speed up execution.</p> <p>The key difference between them is <strong>when</strong> the expansion happens: macros are substituted by the preprocessor before compilation, while inline functions are expanded by the compiler during compilation. However, both result in larger binary sizes compared to using regular functions, since the code is duplicated at every call site.</p> https://blog.gannipiece.tw/en/posts/preprocessor-language/ Wed, 05 Oct 2022 08:30:53 +0000 https://blog.gannipiece.tw/en/posts/preprocessor-language/ The preprocessor runs before the compilation phase. It can handle conditional compilation, file inclusion, macro definitions, and more. In this article, we introduce several types of preprocessor directives, such as Conditional inclusion and Replacing text macros.
