C语言编写一个简单的航空管理系统

C语言编写一个简单的航空管理系统,第1张

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={<ai-1,ai>|ai-1,ai∈D,i=1,2,3...,n}

基本 *** 作:

InitList_Sq(&L)

*** 作结果:创建空的顺序表。

CreatList_Sq(&L)

*** 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={<ai-1,ai>|ai-1,ai∈D,i=1,2,3...,n}

基本 *** 作:

InitList_L(&L)

*** 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z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")

printf("\t*\t3---Adding flight\t4---Adding flight *\n")

printf("\t*\t5---Modify \t6---Advice*\n")

printf("\t*\t7---Save \t8---exit *\n")

printf("\t##########################################################\n")

}

scanf("%s",num)

if(strcmp(num,"0")==0)

break

while(s)

{

if(strcmp(s->data.num,num)==0)

{

printf("=====tip:the number'%s'has been born!\n",num)

return

}

s=s->next

}

p=(Node*)malloc(sizeof(Node))/*航班数据输入*/

strcpy(p->data.num,num)

printf("Input the city where the plan will reach:")/*飞机到达地城市*/

scanf("%s",p->data.city)

getchar()

(已修改,请用最新的代码)代码说明:

1级菜单:选择购买的航班号,并显示对应座位状态。

(我只做测试,所以初始化initFlight函数中我只初始了2个航班,需要自己按照我的代码添)

(注意:实际开发软件,链表数据是从数据库中读取的,需要实时同步,如果要多次调用initFlight函数,记得自己写一个释放内存的函数,把所有链表“SINFO和FLINFO”节点都释放掉,释放函数我没写,需要你自己写!!!)

2级菜单:选择购买对应座位号,完成购买,并实时显示购买结果。

位置编号、座位最大排数、舱室类型、折扣等参数均由常量参数空值,需要修改自行改常量。

注意:舱室类型(我默认3个类型头等舱、公务舱、经济舱)对应折扣参数:tDiscount二维数组。如要如要添加新的舱室类型,必须将参数常量TYPESIZE、typeName、types、tDiscount这4个同时修改,具体看代码备注!!

座位票价=基础票价*类型折扣*时段折扣。

因为飞机不让吸烟,所以我没做吸烟区(笑),如果你需要,可以作为类型自行添加!
