Added a parameterless constructor for inheritance purpose.

As the data members are private, how are you going to set these from a derived class?

Chris--A commented 8 years ago

I'm quite happy to make the members protected so they can be modified by a derived class, I'm just not sure what benefit you'll get with an empty constructor as it is now.
