Thanks. I am reading/referring to a PDF copy of Thinking in C++ but of course 
without knowing the name of this syntax "initializer list" I cannot search 
through the PDF.

Now what I would like to know is: Is

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

much different from:

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

? Seeing as X and Y are not const-s, I do not see the point in initializing 
outside the (empty) braces. If they were const-s, TICP tells me that they 
must be initialized before the *start* of the function so the X(0) syntax is 
necessary. But here they are not const-s...
