C++ How to slow down the execution of a while loop?

Question

C++ / C#

I have a loop:

while(y != 20)
{
    y++;
}

How can I make it increase by one every second?
That is,
1
(one second)
2
(one second)
Etc.

Answer 1

#include <thread>

int main(int argc, char** argv)
{
  int y = 0;
  while (y >= 20)
  {
    std::this_thread::sleep_for(std::chrono::seconds(1));
    y++;
  }

  return 0;
}
