Initialize an static array in a class

[RCAJ]

How can I do the following?

class C{
private:
static const char c[3] = {1,2,3};
//...
};

The compiler says it can't be done like that.

Hello,

How can I do the following?

class C{
private:
static const char c[3] = {1,2,3};
//...
};

The compiler says it can't be done like that.

Static variables should be initialized from outside class.

Yeah, those up-tight compilers can be really retentive, you know?


class C
{
static const char c[ 3 ];
};

const char C::c[ 3 ] = { 1, 2, 3 };

how?

I just want const values for that array. How can I initialize it so that
when I create an object the values are ready to be used without
initializing them in the constructor?

const char C::c[ 3 ] = { 1, 2, 3 };

Thanks. It already works! But I've got a question: why can I get access
to a private atribute outside the class?

Probably because it's _private_...

static const char c[ 3 ];
};

const char C::c[ 3 ] = { 1, 2, 3 };

You're not really accessing it, you're still defining and initializing
it. The semantics are the same as for any private method. You can
define it outside the class. The defintion doesn't count as an access.
You're not actualling calling the method, or in this case, accessing
the variable.
