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，有人知道上面的代码是怎么回事吗？

我从VC++2008Ex获得了第二行的两个错误：

错误C2059:语法错误：'{‘

错误C2334：“{”之前的意外令牌；跳过明显的函数体

Answer 1

您不能在这样的类中定义变量。

应该是这样的：

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};

声明位于类体中；定义位于外部。请注意，您通常会将类主体放在头中，将定义放在源文件中。
