  double getFree(int time, double distance)

  {

      double starting_price = 13;//起步价

      double starting_distance = 3;//起步里程

      double unit_price = 2.3;//单价

      double actual_price = (time > 23 || time < 5) ? unit_price * 1.2 : unit_price;//夜间单价

      double extra_price = 1;//燃油费

      

      if (distance <= starting_distance)

      else
