    int stop;//use the key in function to stop the exe
        cout<<"key in the years you want to know\n";
            cin>>year;
         cout<<"key in the days in a year\n";
            cin>>day;
        cout<<"key in the hours in a day\n";
             cin>>hour;
        cout<<"key in the minutes in an hour\n";
            cin>>hour;
        cout<<"key in the seconds in a minute\n";
