Is vector a; right in C++?

Question

Is vector<int[3]> a; valid C++ ?

Can this cause problems?

Yes , it's fine, but you may prefer `std::vector>` for various reasons. — Dietrich Epp, Aug 27 '17 at 07:24

I tried just now...

It can't be compiled successfully on VS.

But if I only code vector<int[3]> a;, and don't use this vector, it can be compiled successfully.

That's exceedingly inaccurate. It's about *how* you use the vector. Some operations cannot be supported for a type like `int[3]`. – StoryTeller - Unslander Monica Aug 27 '17 at 07:39
