Answer 1

This work for me on Windows try it

#include <csignal>
#include <iostream>
#include <ostream>
#include <string>
using namespace std;

namespace
{
    volatile sig_atomic_t exit;

    void signal_handler(int sig)
    {
        signal(sig, signal_handler);
        exit= 1;
    }
}

int main()
{
    signal(SIGINT, signal_handler);
    signal(SIGTERM, signal_handler);
#ifdef SIGBREAK
   signal(SIGBREAK, signal_handler);
#endif


   while (!exit)
   {
       /* do something */
   }
   // Catch signal here
}
