As for why I need it
In java , I could easily do
public interface Constants {
public static final float BRICKWIDTH = 20.0;
public static final float XLENGTH =20.0;
public static final float GAMEWIDTH = BRICKWIDTH * XLENGTH;
}
and then
public class GameBoard implements GameConstants {
//
}
I need to do this in c++, but non-integral type can't be initialized within a
class.
Any way around this?
Thanks
