c - 在 C 和程序问题中将数组作为函数参数传递

Question

情况

一家小型航空公司刚刚为其新的自动预订系统购买了一台计算机。总统要求你为新系统编程。您将编写一个程序来为航空公司唯一飞机的每个航类分配座位(容量:10 个座位)。您的程序应显示以下替代菜单:请输入 1 表示“头等舱”

请输入 2 表示“经济”如果该人输入 1，那么您的程序应在头等舱分配一个座位(座位 1-5)。如果该人输入 2，那么您的程序应在经济舱分配一个座位(座位 6-10)。然后，您的程序应该打印一张登机牌，标明该人的座位号以及是在飞机的头等舱还是经济舱。使用一维数组来表示飞机的座位表。将数组的所有元素初始化为0，表示所有座位都是空的。当每个座位被分配时，将数组的相应元素设置为 1 以指示该座位不再可用。当然，您的程序永远不应该分配已经分配的座位。当头等舱已满时，您的程序应询问该人是否可以被安排在经济舱(反之亦然)。如果是，则进行适当的座位分配。如果不是，则打印消息“下一趟航类将在 3 小时后起飞。”

问题:我的代码有什么问题才能使其正常工作。

在使用 if 语句进行比较时，必须使用“==”而不是“=”。

将数组作为参数传递时，只需在函数调用中键入名称，并在函数定义中定义一个没有大小的数组。
