程序代码：

interface ICar
    {
        int X { get; set; }
        int Y { get; set; }
        void Eng();
        void Stop();
    }

    class Car : ICar
    {
        public Car(int X, int Y)
        {
            this.X = X;
            this.Y = Y;
        }

        public int X
        {
            get;

        public int Y
        {
            get;
            set;

        public void Eng()
        {
            Console.WriteLine("我有{0}个位置，{1}个轮胎，我要启动了", X, Y);
        }

        public void Stop()
        {
            Console.WriteLine("停车");
