1.请帮我把deleteCar()写完，要求是：
找到registration_nuim然后，要求是再删除车的时候，将所有的元素搬到右边去，一个位置到左边。 例如如果共有五辆车，希望删除第三辆车，第四辆车必须移动第三辆的位置，第五辆车覆盖第四两个车的位置。如果没有找到registration_num，错误的信息提示。
2.最后请把我把exitSystem()写下。
3.顺便能帮我改下Menu的内容谢谢。
4.写一个函数，显示所有车的信息在showRoom里面

printf("1.Add a new car into the showroom :\n"); //按1就会addCar()
printf(" 2.Delte speicific car in the showroom :\n");//按2就会deleteCar()
printf(" 3.View all cars in the showroom \n"); //按3就会displayCar()
printf(" 4.View a speicific car in the show room \n");
printf(" 5.Exit the system");//退出系统
如果太长了，请发到我百度消息

VC编译通过，不好意思，答案修改过一次，5个功能都简单试过，没问题。你自己看看吧，希望对你有帮助。另：如果你学过链表的话，把showRoom数组换成链表，效率会提高很多！

你会97年的第三题骑士游历问题，跪求啊，救命用啊谢谢啊，回头给积分，要多少给多少，谢谢

骑士游历（1997年全国青少年信息学（计算机）奥林匹克分区联赛高中组复赛试题第三题）
设有一个n×m的棋盘(2<=n<=50,2<=m<=50),如图1,在棋盘上任一点有一个中国象棋马，

参考技术A 图1？呢………………
