C99 has finally got named components, though. Consistent with the
language, it doesn't seem necessary to give a value to all components
of C's equivalent of aggregates:

struct foo
{
  int real_part;
  int surreal_part;
};

typedef struct foo Foo;

Foo plus(Foo a, Foo b)
{
  const Foo result =
    {
      .real_part = a.real_part + b.real_part,
      // .surreal_part = a.surreal_part + b.surreal_part // fine?
    };
  return result;
}
