数据结构(C语言)实验报告-飞机订票系统

.数据结构课程设计报告一、 订票系统【需求分析】本订票系统要能够实现航班情况的录入功能、航班的查询功能、订票功能、退票功能以及管理本系统的功能即能够修改航班信息。具体分析如下：1、录入功能可以录入航班信息，如录入航班号，到达城市，起飞时间，飞机票数，票价。2、查询功能可以查询航班的各项信息，如可以查询起降时间，起飞抵达城市，航班票价，确定航班是否满仓，航班号。3、订票功能可以订票并且记录下乘客的相关信息如记录下乘客姓名，身份证号码，所订航班的航班号以及所订的票数。4、退票功能可以退票并且记录乘客的相关信息以及退票信息。5、修改功能可以根据需要由管理员对航班信息进行修改更正。【概要设计】1、算法设计：每个模块的算法设计说明如下：（1）录入模块： 查找单链表的链尾，在链尾插入一个“航班信息”的新结点。（2）查询模块：提供两种查方式：按航号和按航线查询，1代表按航号查询，2代表按航线查询。0则表示退出查询。顺着单链表查找，如果与航班号（航线）一致，输出相关信息，否则，查询不成功。（3）订票模块：查找乘客要订的航班号，判断此航班是否有空位，有则输入乘客有关信息，订票成功，否则失败。（4）退票模块：输入要退票的乘客姓名以及证件号码，查找乘客资料的链表中是否有这位乘客，有则删去此结点，并在空位加上1，无则退票失败。（5）修改模块： 输入密码，确认是否有权限对航班信息进行修改，有则在航班信息链表中查找要修改的结点，进行修改，否则不能修改。2.存储结构设计：（1） 航班的信息：为了便于查找和修改，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、起飞达到的时间、空座和目的的、票价以及限座七个数据项：航班号起飞时间达到时间目的地限座空座票价hD1D2D3单链表如下：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 air_num10; /*航班号*/char start_time15; /*起飞时间*/char end_time15; /*到达时间*/char end_place30; /*目的地*/int total; /*限座*/int left; /*空座*/int price; /*票价*/struct flightnode *next; /*指向个结点*/flightnode;（2） 旅客的资料：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、证件号码、航班号和座位号四个数据项：旅客姓名证件号码航班号座位号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 /*定义乘客资料结点*/char name20;char ID_num20;char air_num20;int seat_num;struct passengernode *next;passengernode;【详细设计】本系统源程序如下：#include#include#define OK 1#define ERROR 0typedef struct flightnode /*定义航班信息结点*/char air_num10;char start_time15;char end_time15;char end_place30;int total;int left;int price;struct flightnode *next;flightnode;typedef struct passengernode /*定义乘客资料结点*/char name20;char ID_num20;char air_num20;int seat_num;struct passengernode *next;passengernode;flightnode *head_flight();
