Yes.

Right.

The C standard guarantees that the non-initialised members of a partially
initialised statically allocated integer array are initialised to zero. C99
Section 6.7.8.10 subclause 2 about arithmetic types. What comes to
automatically allocated arrays, we should avoid them as we are running in a
very limited RAM space.
