需要分析：
A.车寻航线：
1.根据旅客提出的起点站，终点站名输出下列信息：航班号，票价，折扣，最多载客量，是否满载，起飞时间，降落时间和飞行时间；
2.根据订票乘客的姓名可以查询所订航班的航班号，座位号，飞行日期等信息；
3.根据航班号查询航班的起点站，中转站，终点站名，票价，折扣，最多载客量，是否满载，起飞时间，降落时间和飞行时间；
B.承办客户提出的要求（航班号、订票数额）查询该航班票额情况，若有余票，则为客户办理订票手续，输出座位号，需付款项信息；若已满员或余票额少于盯票额，则需重新询问客户要求。若需要，可登记排队候补；
C.根据客户提供的情况（日期、航班），为客户办理退票手续。（然后查询该航班是否有人排队候补，首先询问排第一的客户，若所退票额所能满足他的要求，则为他办理订票手续，否则依次询问其他排队候补客户）；
E.内部人员对航班情况的控制：
可以录入航班信息，删除航班信息，修改航班信息，查看基本航班信息。
概要设计：
因为每个客户名单或查询名单都包括多个数据域，这样就需要有一个能存储多个数据域的数据类型来存储，因此采用单链表类型。由于航线的信息是固定的，可选用结构体数组，又因为订票与预约人数无法预计，可选用链表存储信息。
线性表的单链表存储结构：typedef struct LNode{
ElemType;
Struct Lnode*next;}LNode,*LinkList;
a.抽象数据类型顺序表的定义如下：
ADT SqList{
数据对象：D={ai|ai∈数据类型，i=1,2,3...,n}
数据关系：R1={
基本操作：
InitList_Sq(&L)
操作结果：创建空的顺序表。
CreatList_Sq(&L)
操作结果：建立顺序表。
}ADT SqList
b.抽象数据类型单链表的定义如下：
ADT LinkList{
数据对象：D={ai|ai∈结构类型，i=1,2,3...,n,n>0}
数据关系：R1={
基本操作：
InitList_L(&L)
操作结果：创建空的顺序表。
}ADT LinkList
在main()里调用各个函数
2．主程序
void main(){
初始化；
do{
接受命令；
处理命令；
}while(“命令”！=“退出”)；
}
3．程序的模块调用：
三．详细设计：
1．所有数据类型：
struct plan /*航班数据*/
{
char num[5];/*航班号码*/
char city[10];/*到达城市*/
char up[8];/*航班起飞时间*/
char down[8];/*航班到达时间*/
int pric ;/*航班价格*/
int rshu ;/*人数*/
int zheg[4];/*价格折扣*/
}
;
struct man/*定票人数据*/
{
char num[10];/*身份证号码*/
char nam[10];/*姓名*/
int demand ;/*定票数量*/
}
;
typedef struct node/*航班数据结点*/
{
struct plan data ;
struct node*next ;
}
Node,*Link ;
typedef struct people/*乘客数据结点*/
{
struct man data ;
struct people*next ;
}
peo,*LIN ;
2．程序所用函数：
void print()/*界面输出*/
{
printf("============================System of book ticket===============================\n");
printf("\n");
printf("\t***********************************************************\n");
printf("\t*\t1---Bookticket \t2---Dishonorbill *\n");
