C语言内核链表实现航班管理系统：展示、修改、新增和删除航班信息
这段代码实现了一个简单的航班管理系统，使用内核链表来存储航班信息。可以通过菜单选项进行航班的展示、修改、新增和删除操作。

代码解释
-
数据结构定义
Flight结构体：用于存储航班信息，包括航班号、始发地、目的地、出发时间、到达时间、金额和乘客人数。Node结构体：用于构建链表节点，包含一个Flight结构体和指向下一个节点的指针。
-
函数定义
createNode(Flight flight)：创建一个新的节点，并初始化节点的航班信息。insertNode(Flight flight)：将一个新的航班信息插入到链表中。displayFlights()：遍历链表，显示所有航班信息。updateFlight(char flight_no[10], char departure_time[6], char arrival_time[6], float amount)：根据航班号查找航班信息，并更新出发时间、到达时间和金额。addFlight()：添加新的航班信息到链表中。deleteFlight(char flight_no[10])：根据航班号删除指定航班信息。
-
主函数
- 初始化五个航班信息。
- 使用
do-while循环构建菜单，用户可以选择展示、修改、新增和删除航班信息，以及退出系统。
总结
这段代码提供了一个简单的航班管理系统的实现，使用了 C 语言中的内核链表来存储航班信息，并支持常见的航班管理功能，包括展示、修改、新增和删除。 可以通过修改代码来添加更多的功能，例如查询航班信息、排序航班信息等。
优化建议
- 可以使用
typedef定义链表节点类型，使代码更简洁。 - 可以使用更健壮的输入验证方法，避免输入错误导致程序崩溃。
- 可以添加更多功能，例如查询航班信息、排序航班信息等，使其更实用。
- 可以考虑使用文件存储航班信息，使其持久化。
