C++一分钟之-C++中的枚举类型(enum class) 腾讯技术创作特训营S7 在C++编程中,枚举类型是一种定义常量集合的方式,用于提升代码的可读性和维护性。自从C++11引入了enum class(也称为强枚举类型或scoped enumeration),它在原有枚举类型的基础上增加了作用域限制和类型安全,从而减少了命名冲突和类型混淆的风险。本文将...
Scoped enums (enum class/struct) are strongly typed enumerations introduced in C++11. They address several shortcomings of the old C-style (C++98) enums, mainly associated with type-safety and name collisions. Consequently, the C-style enums are now known as unscoped enums, and that is h...

C++/CX supports the public enum class keyword, which is analogous to a standard C++ scoped enum. When you use an enumerator that's declared by using the public enum class keyword, you must use the enumeration identifier to scope each enumerator value....
