const double delay1 = 2 * microToSeconds; //2 seconds
const double delay2 = 4.5 * microToSeconds; //4.5 seconds
cout<<"Delay 1 in progress... ("<<delay1/microToSeconds<<"s)"<<endl;
usleep(delay1);
cout<<" => Delay 1 is over"<<endl<<endl;
cout<<"Delay 2 in progress... ("<<delay2/microToSeconds<<"s)"<<endl;
usleep(delay2);
