How to suspend the main and only thread in C++?

Question

Programming

I want to make a watch. I only need to put the main thread to sleep for a second. How can I do it? I didn't find anything on the Internet.

Answer 1

C++11:

std::this_thread::sleep_for(std::chrono::seconds(1));

Answer 2

It's strange that they didn't find it. For Windows - Sleep(1000), for example.
