C++, Using iostream library to output an uninitialized variable \ Visual Basic

Question

How can I make Visual Studio (2019) print an uninitialized variable?

#include <iostream>

int main()
{
  int x;
  std::cout << x;
  return 0;
}

I understand this is relatively useless and uninitialized variables should not normally be used, but I would imagine there should be a way to make it print the value in the random mem location.

Error Code: C4700 - uninitialized local variable 'x' used

Answer 1

There is a method to do it.

int main()
{

    int num[1];
    for (int i = 0; i < 1; i++)
    {
        std::cout << num[i];
    }
}

In my opinion, outputting uninitialized variables does not make much sense. Maybe you want to get the address.

int x;
std::cout << &x;
