simple constructor question

[mjl3434]

I'm writing a simple game application. A game object is composed of a Board and an AI player. When the AI player is constructed it needs a reference to a board object, so it can interact with it. How can I set up the game class so that its members get constructed properly--considering that one needs a reference to another?

class Game
{
    private:
        Board theBoard;
        AI computerPlayer;  // AI needs reference to theBoard (above)
};

class AI
{
    AI(Board& board_in) : theBoard(board_in)

    private:
        Board& theBoard;
};
