课程设计---飞机订票系统

1. 题目

本课程设计的题目为：飞机订票系统。

2. 项目描述

基于目前人们外出远行频繁，为方便乘客提前买票及优化飞机航空订票服务，需要开发一个飞机订票系统，此程序就是要实现航班情况的录入，查询，订票，退票以及航班的查询和修改等基本功能。

3. 数据及其逻辑结构分析

（1）航班的信息：航班的情况存储结构采用单链表，每个元素表示一个航班的情况，包括航班号、起飞时间、降落时间、起飞城市、抵达城市、航班票价、票价折扣、确定航班是否满仓和空座数九个数据项：

航班号

起飞

时间

降落

时间

起飞

城市

抵达

城市

航班

是否满仓

空座数

票价

折扣

字符串

整数

（int）

整数

（int）

浮点数

（float）

浮点数

（float）

每个结点包括数据域和指针域：

数据域

指针域

C语言描述如下：

typedef struct flightnode{

　char flight_num[10];//航班号

　char start_time[10];//起飞时间

　char end_time[10];//抵达时间

char start_place[20];//起飞城市

　char end_place[20]; //抵达城市

　int left; //空座数

float price; //票价

float price_discount;//票价折扣

int isFull; //航班是否满仓

　struct flightnode *next;//指向下一个结点

}flightnode;//航班结点

（2）客户的资料：为了便于插入、删除和修改，其采用单链表存储结构，每个数据元素包括姓名、证件号、航班号、订票数量和订单号五个数据项：

姓名	证件号	航班号	订票数量	订单号
字符串	字符串	字符串	整数（int）	整数（int）

每个结点包括数据域和指针域：

数据域

指针域

C语言描述如下：

typedef struct passengernode{//定义客户资料结点

　char name[20]; //姓名

　char ID_num[20]; //证件号

　char flight_num[10];//航班号

int order_num; //订单号

　int ticket_num; //订票数量

　struct passengernode *next;//指向下一个结点

}passengernode;/客户结点

（3）客户链表：每个数据元素包括头指针和尾指针两个数据项：

每个结点包括两个指针域：

头指针域

尾指针域

C语言描述如下：

typedef struct passengerList{

　passengernode *head;

　passengernode *rear;

}passengerList;

4. 数据的存储结构设计

程序运行时会从文件中将航班数据调入内存，并且以单链表的存储方式进行存储。每个链表结点的数据域有一个用户自定义结构体组成，结构体内包含有详细的航班有关信息。

5. 系统模块组成

1 录入航班信息模块

void add_flight(flightnode *&h)调用void insert_flight(flightnode *&h,char* flight_num,char* start_place,char* end_place,char* start_time,char* end_time,int left,float price,float price_discount,int isFull)函数，将新航班结点插入航班链表中。

2 客户订票模块

int book(flightnode *&h,passengerList *&PList)函数调用int insert_passenger(passengernode *&h,char *name,char *ID_num,char *flight_num,int ticket_num,int order_num)函数，将新客户结点插入客户链表中。

3 客户退票模块

void cancel(passengerList *&PList,flightnode *&h)函数调用int delete_passenger(passengerList *&PList,flightnode *&h,char *name,char *ID_num)函数，将相应的顾客结点删除，并修改相应的航班信息。

4 查询航班模块

void flight_check(flightnode *h)调用void check_all_flight(flightnode *h)函数进行所有航班信息浏览，调用int place_check(flightnode *h,char *start_place,char *end_place)函数按起飞抵达城市对航班进行查询，调用int flight_num_check(flightnode *h,char *flight_num)按航班号对航班进行查询。

5 查询订单模块

void passenger_check(passengerList *PList)调用void check_all_passenger(passengerList *PList)函数进行所有订单信息浏览，调用int order_num_check(passengerList *PList,int order_num)函数按订单号对订单进行查询，调用int ID_name_check(passengerList *PList,char *name,char *ID_num)按客户姓名和证件号对订单进行查询。

6 修改航班模块

增加航班时，void modify_flight(flightnode *&h,passengerList *&PList)函数调用void add_flight(flightnode *&h)函数，将新航班信息结点插入航班链表中。

删除航班时，void modify_flight(flightnode *&h,passengerList *&PList)函数调用void delete_flight(flightnode *&h,passengerList *&PList)函数将相应的航班信息删除,并删除相应的订单信息。

修改航班时间时，void modify_flight(flightnode *&h,passengerList *&PList)函数修改指定航班的起飞抵达时间。

课程设计总结

经过这几天的数据结构课程设计，我收获很大，在实现系统功能的过程中，也遇到很多问题，及时的向周围的同学请教，寻求帮助，设计修改，编写调试，每一步都渗透着沟通和分析，每一次沟通之后，都会对系统功能有更深层次的理解和阐述，这也促使我一步步完成了整个系统，并使之可以运行。时间太短暂了，我没有办法把全部学到的知识运用到具体的系统实现中，深深感受到数据结构这门课程的重要性，以及它在实际应用中的广泛性。这个飞机订票系统由于种种原因仍然存在需要改进，需要完善的地方，我对于这个系统的认识和对数据结构这门课程的理解已经更加深入了。在实现系统的过程中，我感受到自己的知识的薄弱零散，经过这次做系统，我觉得自己的知识得到巩固和整合，知识体系更加系统化。我也深深体会到实践检验真理，只有实践中，才能出真知。我懂得了学习不只是纸上谈兵，更重要的是实践，就比如平常我们在学习中经常会遇到一些问题，看似无关紧要跳过去，不求甚解，在得知答案的时候，总是感觉心领神会，久而久之，对于的知识点就模棱两可，形成知识漏洞。但这次课程设计所要编写的程序很长，涉及的知识点也很多，选择此题目的时候我心里面还底气十足，自认为没什么问题，对于程序的步骤仿佛了然于胸，但在实际操作中才发现并非如此，在编写程序的过程中，我不断地上网查阅相关资料进行学习，积极地思考该怎样实现系统的每一个功能。

通过这次数据结构的课程设计，我巩固和加深对数据结构基本知识的理解，锻炼了综合运用课本知识的能力，自己也真正地完整而系统地设计并编写了一个程序，使得自己的编程能力大为提高。通过对我所选择飞机订票系统的设计和编写，我初步掌握简单软件的分析方法和设计方法，第一次体会到了数据结构编程知识在实际生活中的重要性和应用的广泛性，最后，我要感谢老师和同学们，正是因为他们的热心帮助，我才能正确的完成这次课程设计。在今后的学习和工作中，会更加深入地把知识和思想体会更广泛地应用到其他学科的学习中。
