new class structures are zero initialized and pre-filled with the contents
of the parent class. instance structures and instance private data is
zero initialized.

however, it is a good habit to initialize all fields explicitely, getting used to this
comes in handy if you switch to other languages like C++ which don't do automatic
zero initialization.
