C++数组初始化器.使用枚举类型

Question

class ARouter {
    enum directions {north, neast, east, seast, south, swest, west, nwest};
    static directions gon[] = {north, neast, nwest, east, west, seast, swest, south};
};

嗨,有谁知道上面的代码是什么问题？

我从VC++ 2008Ex获得第二行的2个错误:

错误C2059:语法错误:'{'

错误C2334:'{'之前的意外标记; 跳过明显的功能体

Answer 1

您无法在类中定义变量.

它需要是这样的:

class ARouter {
    enum directions {north, neast, east, seast, south, swest, west, nwest};
    static directions gon[];
};

ARouter::directions ARouter::gon[] = {north, neast, nwest, east, west, seast, swest, south};

该声明进去类体; 这个定义存在于外面.请注意,您通常将类主体放在标头中,并将定义放在源文件中.
