c++ usleep()

using namespace std;

    const int microToSeconds = 1000000;   
    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);
    cout<<"  => Delay 2 is over"<<endl<<endl;
