Of course.
See ISO 9899:1999, section 6.7.8.
Paragraph 10:
If an object that has automatic storage duration is not initialized
explicitly, its value is indeterminate. 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.
Paragraph 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.
