Easy problem in class B: data is null!

Since abc isn't initialized in this constructor, abc.ptr is null. 
So data is null too.


        public void print()
        {
                for(size_t i = 0; i < 4; i++)
                {
                        writefln("%d", data[i]);
                }
        }
}


And since data is null, data[i] will be a memory 
err/segfault/access violation/whatever it is called.
