Not the whole structs but the missing fields are zero'd:

"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."
