课堂上要求设计这个程序

应该如何设计呢

参考代码如下：

如有帮助，请采纳一下，谢谢。

#include <iostream>

}

//按日期和航班号显示订票人

	Date dd;
	string p;
	bool b = false;

		case 2:

			break;
		case 3:

			break;
		case 4:
			Show(info);
			break;
		case 9:
			isWork = false;
			break;
		}
	}
	
	return 0;
}

思路：

1.定义订票信息的数据结构数组；

2.用print方法输出主菜单；

3.每个菜单对应一个实现方法。
