会导致编译错误，因为 `using` 不支持直接给匿名 `enum` 重新命名。在这种情况下，你可以使用 `typedef...
在C++11中,新增了using enum语法,用来为枚举类型定义别名,例如: #include <iostream> enum class Color { RED, GREEN, BLUE }; using ColorType = Color; int main() { ColorType c = Color::RED; switch (c) { case Color::RED: std::cout << "Red" << std::endl; break; case Color::GREEN...
usingstaticColor;enumColor { Red, Green, Blue }classProgram{publicstaticvoidMain(){ Color color = Green; } } 别名using 创建using别名指令,以便更易于将标识符限定为命名空间或类型。 在任何using指令中,都必须使用完全限定的命名空间或类型,而无需考虑它之前的using指令。using指令的声明中不能使用using别...
在C++编程中,类型别名和using声明是两个非常实用的功能,它们可以提高代码的可读性和维护性。本文将深入浅出地介绍这两个概念,包括它们的常见用法、易错点以及如何避免这些错误。 1. 类型别名 类型别名(Type alias)允许我们为已存在的类型创建一个新的名称。这在处理复杂的类型表达式时特别有用,可以使代码更清晰、更...
typedef enum {..} AnEnum** Enum: AnEnum * If the C Caller takes an integer type, for example, int16_t, you can modify it to a fixed-point type with matching base type, for example to fixdt(1, 16, 3). ** The C Caller sync button prompts you to import struct or enum types ...
.NET Microservices Architecture for Containerized .NET Applications | Lear how you can use enumeration classes, instead of enums, as a way to solve some limitations of the latter.
