用c语言实现显示航班管理系统中的乘客信息座位号

好的，要实现显示航班管理系统中的乘客信息座位号，可以按照以下步骤：

1. 在程序中定义一个结构体，包含乘客的姓名、座位号等信息，例如：

struct passenger {
    char name[20];
    int seat_num;
    // 其他信息
};

2. 在程序中定义一个数组，用来存储所有乘客的信息，例如：

struct passenger passengers[100];

这里假设最多有100个乘客。

3. 在程序中读取乘客的信息，例如：

for (int i = 0; i < 100; i++) {
    printf("请输入第%d个乘客的姓名和座位号：", i + 1);
    scanf("%s %d", passengers[i].name, &passengers[i].seat_num);
    // 其他信息的读取
}

这里假设乘客的姓名不超过20个字符。

4. 在程序中显示乘客的信息和座位号，例如：

for (int i = 0; i < 100; i++) {
    printf("第%d个乘客的姓名是：%s，座位号是：%d\n", i + 1, passengers[i].name, passengers[i].seat_num);
    // 其他信息的显示
}

这样就可以实现显示航班管理系统中的乘客信息和座位号了。当然，实际的航班管理系统可能会更加复杂，需要根据具体的需求来进行设计和实现。

}

该系统实现了不同车次信息的添加、删除、修改等功能；所有车次余票显示；查询车次、余票、票价等功能；选择座位、填写乘客信息、预订车票等功能。

用C语言来实现：将所有数据以文件保存，用子函数实现各个子功能 (1) 航班的增加与删除功能。 (2) 航班查询功能：按航班号来查询所有航班信息，根据航班号查询订票乘客信息等列出该航班已订票的乘客名单。 (3) 航班订票功能：根据航班号为客户订票。 (4) 航班退票功能。 (5)显示功能：输入查询所有消息，即可显示出所有航班信息（航班号、出发地、目的地、乘客姓名、身份证号码、订购座位、航班余票），并统计出有多少条记录并且显示出来（所有航班的信息一起统计）

该程序通过结构体和指针实现了航班的增加、删除、查询、订票、退票以及显示所有航班信息的功能，并且将所有数据保存在内存中。如果需要将数据保存到文件中，可以使用文件读写函数来实现。
