So from C99 standard ยง6.7.8 (Initialization)/21:
"If there are fewer initializers in a brace-enclosed list than
there are elements or members of an aggregate, or fewer characters
in a string literal used to initialize an array of known size than
there are elements in the array, the remainder of the aggregate
shall be initialized implicitly the same as objects that have static
storage duration."
static initialization == zeroing in this case.
Thanks,
