C++ array initializer. Using enum type

Question

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

Hi, does anyone know what is the matter with the above code?

I am getting 2 errors for the second line from VC++2008Ex:

error C2059: syntax error : '{'

error C2334: unexpected token(s) preceding '{'; skipping apparent function body

There is nothing wrong with those lines. You probably have a syntax error further up the file, which is causing the compiler to become confused. Or perhaps you're defining the variable somewhere invalid, like inside a class body. — Oliver Charlesworth

You sure? I just bracketed it off into a little class for completeness. I haven't really changed anything else to break it. I'll take the lines out and try again. brb. — John

You cannot define a variable inside a class like that.

It needs to be something like:

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};

The declaration goes in the class body; the definition lives outside. Note that you'd typically put the class body in a header, and the definition in a source file.

The pseudonym "class variable" mislead me in this case.
