Inconsistent object initialization?

struct RandomStruct {
  RandomStruct(int a) {

  }
}

int main() {
  RandomStruct works();
  RandomStruct doesntWork = RandomStruct();
  RandomStruct doesntWork2{};
}

Why is it that the second two intitializations don't work, but the first does? Should I use one form over another? This behaviour is rather bewildering to me.

Thanks!

Because the 1st one is a function declaration. Try `RandomStruct doesntWork3;`. – songyuanyao Jul 07 '21 at 03:34
Ohhhhhhh, that makes a lot of sense. In this case is it correct to say that `RandomStruct works()` is simply incorrect, because C++ does not allow for function declarations inside functions? – Each One Chew Jul 07 '21 at 03:38
No it's allowed. That's why it compiles fine. – songyuanyao Jul 07 '21 at 03:43
