Is there ways for my program, that can force my program wait maybe 5 sec and only then I can enter with cin>>"" (C++)

Answer 1

#include <iostream>
#include <thread>
#include <chrono>
using namespace std;
int main()
{
cout << "program paused for 5 seconds" << endl;
this_thread::sleep_for (chrono::seconds(5));
cout << "Timer finished";

return 0;
}
