C++ has from the beginning attempted to improve on the type system of C, adding features like classes that let you build better types and enums, which eliminate the need for some uses of the preprocessor (which is not at all type safe). C++ also performs fewer implicit type conversions ...
Better Enums - Reflective enums (to string, iteration). Single header. [BSD] website clReflect - C++ Reflection using clang. [MIT] CPFG - A C++03 library for reflection, callback and script binding. [Apache2] CPP-Reflection - C++ Reflection using clang. [MIT] Easy Reflection - Easy an...
模組現已正式使用 C++20 標準。 Visual Studio 2017 15.9 版已新增改善的支援。 如需詳細資訊,請參閱 Better template support and error detection in C++ Modules with MSVC 2017 version 15.9 (C++ 模組與 MSVC 2017 15.9 版的更佳範本支援和錯誤偵測)。
实际上,如果只是要在D语言中编写类似C的代码,并不需要-betterC开关。只有在没有D Runtime的特殊情况下才需要使用。 静态assert() 这个功能允许开发者在编译时验证一些假设。 代码语言:javascript 代码运行次数:0 复制 Cloud Studio代码运行 staticassert(kNumInducers<16); ...
enum class my_type : size_t {}; Then, change your definition of placement new and delete to use this type as the second argument instead of size_t. You'll also need to update the calls to placement new to pass the new type (for example, by using static_cast<my_type> to convert...
my_enum_testb, } my_enum_t; 在声明时初始化结构时,使用C99初始化风格 /* OK */ a_t a = { .a = 4, .b = 5, }; /* Wrong */ a_t a = {1, 2}; 当为函数句柄引入newtypedef时,使用_fn后缀 /* Function accepts 2 parameters and returns uint8_t */ ...

Avoid "big ideas" & the "more is better" fallacy. Introduce some higher level conveniences where the value is great. C3 owes its inspiration to theC2 language: to iterate on top of C without trying to be a whole new language. Example code ...
