After the release of C++20, they can now use coroutines — functions that can pause execution and resume it later. WebThe C preprocessor modifies a source code file before handing it over to the compiler. You're most likely used to using the preprocessor to include files directly into other files, or #define constants, but the preprocessor can also be used to create "inlined" code using macros expanded at compile time and to prevent code from being compiled ...
WebApr 27, 2024 · The SWAP() macro example seems a bit contrived. Such a macro would either declare a temporary (and use an extension like __typeof__ to determine its type from the arguments) or be implemented as an (inline) function.
