C++11 中,枚举的关键字为 enum class,即在 enum 后加 class,与 C++98 的 "plain" enum 区别如下: enum class Color { red, green, blue }; enum Color { red, green, blue }; 1 enum class 的优点 1.1 防止命名空间污染 C++98 的 enum 是"非域内枚举"(unscoped enums) // yellow, green, ...
// underlying type is int enum class Status; // underlying type for Status is std::uint32_t (from <cstdint>) enum class Status: std::uint32_t; // specify underlying type on enum's definition enum class Status: std::uint32_t { good = 0, failed = 1, incomplete = 100, corrupt =...

const std::vector<int>::iterator iter=vec.begin(); //相当于iter不能改变 std::vector<int>::const_iterator citer=vec.begin(); //iter所指向的内容无法改变 (2)将函数返回值声明为常量,不仅可以降低因程序员错误造成的不可预料的情况,并且不用放弃安全性和高效性。例如: ...
const std::vector<int>::iterator it = v.begin(); //注意,此声明只表示迭代器本身是常量 *it = 10; //编译通过,迭代器是常量,但数据可以被修改 ++it; //编译失败!因为const迭代器不允许被改变! 解决方法,使用const_iterator: std::vector<int>::const_iterator it = v.begin(); //使用了const_...
