程序的要求是这样的:
某航空公司购买了一台用于航空订票系统的计算机，要求对新系统编程，对每个航班订座（每班10位）。
要求：
程序显示下列菜单选项：
 Please type 1 for “smoking”
 Please type 2 for “nonsmoking”
如果输入1，则程序指定吸烟舱位（座位1到5），如果输入2，则程序指定非吸烟舱位（座位6到10）。程序应输出一个登机牌，表示座位号和是否为吸烟舱位。
提示：
用一个单下标数组表示飞机的座位图。将数组的所有元素初始化为0，表示所有座位都是空的。订每个座位时，将数组相应元素设置为1，表示该座位已订。当然，程序不能再订已经订过的座位。吸烟舱位已满时，应该询问可否订非吸烟舱位；同样，非吸烟舱位已满时，应询问可否订吸烟舱位。如果同意，再相应订座，否则打印消息：“Next flight leaves in 3 hours”。
