Unpacking Arrays C++

In part two of the C++ course in the arrays section it talks about unpacking arrays. I am getting an error saying x idenfier undefined. I have searched online how to do this using the auto keyword and what i come up with is not whats in this video.

// Codewithmosh.cpp : This file contains the 'main' function. Program execution begins and ends there.
//

#include <iostream>

using namespace std;

int main()
{
	int values[3] = { 10, 20, 30 };

	auto [x, y, z] = values;
}

// Run program: Ctrl + F5 or Debug > Start Without Debugging menu
// Debug program: F5 or Debug > Start Debugging menu

// Tips for Getting Started: 
//   1. Use the Solution Explorer window to add/manage files
//   2. Use the Team Explorer window to connect to source control
//   3. Use the Output window to see build output and other messages
//   4. Use the Error List window to view errors
//   5. Go to Project > Add New Item to create new code files, or Project > Add Existing Item to add existing code files to the project
//   6. In the future, to open this project again, go to File > Open > Project and select the .sln file

You do not have a type set for variables x y and z defined. You need at least

char x =0;

or

int x = 0; for all three. The system does not know what type x is, that is why the error.
