A header file contains the following class declaration:

class CAA2DCoordinate
{
public:
//Constructors / Destructors
	CAA2DCoordinate(): X(0), Y(0) {};

//member variables
  double X;
  double Y;
};

Now what I do not understand is the line:

	CAA2DCoordinate(): X(0), Y(0) {};

I would have thought it would be:

CAA2DCoordinate() { X = 0; Y = 0; }

just like the QDate constructor:

    QDate() { jd = 0; }

What is the meaning of the colon ":" here, and what are the (0) things, and 
why are X and Y *outside* the braces?

Thanks for your patience.
