It probably does not look very well, but otherwise correct:

> If an object that has static storage duration is not initialized explicitly, then:
> — if it has pointer type, it is initialized to a null pointer;
> — if it has arithmetic type, it is initialized to (positive or unsigned) zero;
> — if it is an aggregate, every member is initialized (recursively) according to these rules;
> — if it is a union, the first named member is initialized (recursively) according to these rules.
