    Initializing static const memebers in a class

    I have a class that has a static const member variable in it. The variable is anouther class. I know you can't initialize it inside the class so how would I go about doing that?

    Posting code helps.
    Code:
    class T
    {
       static const double pi;
    };
    
    const double T::pi = 4.0 * std::atan(1.0);
    [edit]
    Code:
    class T
    {
       int i;
    public:
       T(int i_ = 0) : i(i_) {}
    };
    
    class U
    {
       static const T t;
    };
    
    const T U::t = 0;
    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
