Is there a decent way to make a program delay for a certain amount of time?

[Ch1156]

I have always wondered about how to make a program delay for a certain amount of time with just basic C++ and no external libraries if at all possible, cause i know SFML has code to assist with that. I mean you can do something like this:

#include <iostream>

using std::cout;
using std::endl;

int main()
{
	cout << "Hello" << endl;

	for (int i = 0; i < 900000000; i++)
	{

	}

	cout << "world" << endl;
}

But that may run faster or slower depending on your CPU(I have an i7-9700k so this takes like 1/12-2 seconds to run), I dont really know. I dont want to use stuff like sleep or pause. What would be a good way to accomplish this?

Im not using it in a program or anything im just curious.
