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。总裁要求您对新系统进行编程。您将编写一个程序，在航空公司唯一的飞机的每次飞行中分配座位（容量：10个座位）。您的程序应显示以下替代菜单：请为“头等舱”输入1

请输入2作为“经济” 如果人员输入1，则您的程序应在头等舱部分中分配一个座位（座位1-5）。如果人员输入2，则您的程序应在经济部分中分配一个席位（6-10位）。然后，您的程序应打印出登机证，指明该人的座位号，以及该座位是在飞机的头等舱还是经济舱。使用一维数组表示飞机的座位图。将数组的所有元素初始化为0，以指示所有席位均为空。分配了每个座位后，将数组的相应元素设置为1以指示该座位不再可用。当然，您的程序应该永远不要分配已经分配的席位。当头等舱部分已满时，您的程序应询问此人是否可以放入经济舱（反之亦然）。如果是，则进行适当的座位分配。如果否，则打印消息“下一次飞行将在3个小时内离开。”

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'='。

在将数组作为参数传递时，只需在函数调用中键入名称，然后在函数定义中定义不带大小的数组即可。

在C和程序问题中将数组作为函数参数传递
