Subject: how to initilize an array inside of a class??

I have a bit of a problem that I can't really see an elegant solution
for and I hope someone can point me in the right direction.  I have
a class that looks something like this:

class Y : public X
{
    public:
        int some_ints[3000];
        Y();
        ...
};

Now what I'd need to do is initilize the array 'some_ints' with some
preset values...normally one would do it like:

int some_ints[3000] = { 1, 6, 34, 3, ... ,0 };

But my compiler complains about that, saying that I can't initialize
class members there.  The only other way I can think of doing it is
to do something like:

Y::Y()
{
    some_ints[0] = 1;
    some_ints[1] = 6;
    ...
    some_ints[2999] = 0;
}

Is this my only other option??  If it is, it's not really all that bad
as this code is being generated by another program, so I won't have to
type in 3000 entries like that, but I was hoping for a more elegant
solution...Would there be a performance hit doing it that way, I kinda
think so as the first one is done at compile time, while the other is
done at run-time, correct??

Any Ideas?
