飞机订票系统（c语言）

一、项目背景

​ 为了免去在窗口排队买票的麻烦，飞机订票系统应运而生。用户通过该系统可以快速，详细地了解需要的信息，并提供了一个很好的购票渠道。

二、设计目的

• 如何合理设计不同数据结构来存储航班信息、旅客信息、订票信息等不同数据
• 如何合理设计不同的链表节点来封装不同的实体信息；
• 如何合理设计多个链表结构来管理不同实体的若干记录；
• 进一步强化学习链表的创建、插入、查找、修改和删除等基本操作；
• 进一步强化学习内存中链表数据和外部文件之间的存取操作；
• 如何利用time.h中的函数获取系统日期时间

三、项目功能需求

1、添加机票信息

• 能够添加机票的航班号、起飞降落时间、目的地、出发地、票价、可定的剩余票数以及折扣信息等。

2、查询可预订的机票信息

• 能够根据用户的具体需求即航班号或目的地，查询可定的机票并输出相应的机票信息，支持标准格式输出多条机票信息。

3、预定机票并输入个人信息

• 查询机票后，根据用户的选择，决定是否订票，并输入信息。

4、修改机票信息

• 能修改已经存在的机票信息。

5、退票

6、根据目的地和最早出发时间，系统可以推荐合适的机票信息

7、显示当前时间

四、系统的功能结构图

五、功能模块介绍

1、添加模块

• 可以连续添加多条航班信息，包括航班号、出发城市、到达城市、出发时间、到达时间、票价、折扣信息、票数

2、查找模块

• 用户在订票之前需要先查询满足自己出行需要的机票信息，本功能模块支持按照“航班号”查询和按照“目的地”查询两种方式

3、订票模块

• 输入目的地信息，可以输出所有满足该目的地的航班信息，并提示用户是否订票

4、修改模块

• 输入需要修改的航班号，可以修改航班信息

5、退票模块

• 能支持用户退票操作

6、显示模块

• 显示模块可以展示所有航班信息，供旅客查看选择

7、推荐模块

• 推荐模块的功能是根据旅客输入的目的地信息和最早出发时间，向旅客推荐满足要求的航班信息，帮助旅客快速搜索符合时间要求的航班

8、保存模块

• 能将航班信息和旅客订票信息保存到磁盘文件中，再次启动系统时，则可以自动读取文件中的航班信息和旅客订票信息

9、时间模块

• 支持实时查询当前时间功能

六、详细设计

1、主函数

功能设计文章来源地址https://www.toymoban.com/news/detail-475230.html

• 主函数用于实现主菜单的显示，并响应用户对菜单项的选择。
• 本系统的主函数主要两大功能:保存信息和菜单选择。
• 某个功能执行完之后，还能按任意键自动回到主菜单，便于用户进行其他操作。

2、添加模块

功能设计

• 用于对飞机班次，始发地，目的地，起飞时间，降落时间，票价，折扣以及所剩票数等信息的输入与保存。

添加模块流程图

3、查找模块

功能设计

• 用于根据输入的飞机班次或到达城市来进行查找，了解航班的信息。
• 提供了两种查询方式:一是根据飞机班次查询，二是根据到达城市查询。

4、订票模块

功能设计

• 用于根据用户输入的城市进行查询，在屏幕上显示满足条件的飞机班次信息。
• 从中选择自己想要预定的机票，并根据提示输入个人信息。

5、修改模块

功能设计

• 用于对已添加的飞机班次，时间，地点，票价等信息的修改。

6、退票模块

功能设计

• 用于用户对已经预定的飞机票进行退票。

7、显示模块

功能设计

• 用于对输入的航班信息和经过修改的航班信息进行整理输出，方便用户查看。

8、推荐模块

功能设计

• 用于对用户提供的信息，系统检索后提供合适的机票，以便用户选择适合自己时间的班次后进行预订。

9、保存模块

功能设计

• 应用文件处理来将航班信息和订票人信息保存到指定的磁盘文件中。

10、时间模块

功能设计

• 为了更好地方便用户订票时的实际需求，本系统提供了查询当地时间的功能。
