航空客运系统代码-课程设计(C语言)

航空客运系统代码-课程设计(C语言)

1.需求分析：

设计一个航空客运系统，该系统能完成的业务活动包括：查询航线、机票预顶和办理退票等。
运行环境：DEV C++；语言：C语言。
(1)、完成的基本要求：
用户层面：查询航线、订购机票、查看所有航班信息。
管理员层面：添加航班、删除航班、查看航班客户订单、查看所有航班信息及退票。
(2)、选做内容：当订票要求不满足时，系统向用户推荐同一目的地的其他航线。
(3)、增加的功能：
1).用户查询根据航班号和姓名查询订单情况。
2).订票时，可输入航班号或者目的地进行查询。
3).根据用户的不同需求提供不同的舱位等级，实行不同的票价。
4).管理员可以查询指定航班的候补乘客人数和名单。
5).管理员进行退票处理时，增加了与用户的交互，符合条件的候补用户可重新选择自己的票数和舱位等级。
6).用随机生成整数的函数，模拟验证码和订单号(经过简单的放大处理)

2.主要流程

3.代码实现

数据结构

//已订票客户的名单，带头结点双向链表实现 
typedef struct clientNodehaha
{
	char name[MAXSIZE];//姓名
	char ID_num[MAXSIZE];//证件号
	char flight_num[10];//航班号
	char time[MAXSIZE];//起飞时间
	int order_num;//订单号
	int amout;//订票数量
	int rank;//舱位等级 
	struct clientNodehaha *behind;
	struct clientNodehaha *head;
}clientList,*clientListL;
clientList *CLient;


//等待候补的客户名单，带头结点单链表 
typedef struct waitNode{
	char name[MAXSIZE];//姓名
	char ID_num[MAXSIZE];//证件号
	int amout;//订票数量

	//int rank;//舱位等级 
	struct waitNode *next;
}waitNode,*waitPtr;
waitNode *Q; 


//航班总信息链表，带头结点的单链表实现 
typedef struct Flight{
	char destination[MAXSIZE];//终点站 
	char flightId[MAXSIZE];//航班名 ，唯一 
	char planeId[MAXSIZE];//飞机号 
	char time[MAXSIZE];//起飞时间 
	float money;
	int num;//乘员余额 
	int tickets;//余票量
	clientListL CLientc;//已订票客户名单 
	waitPtr wqueue;//等候替补的客户名单 
	struct Flight *next;
}Flight,*flightList;
Flight *flight;

对航班的操作

//初始化航班列表 
Status inItFlight(flightList &F){
	clientListL init_passengerList(clientListL &CLient);
	F = (Flight *)malloc(sizeof(Flight));
	if(NULL==F) return ERROR;
	strcpy(F->destination,"");//复制字符串 
	strcpy(F->flightId,"");
	strcpy(F->planeId,"");
	strcpy(F->time,"");
	F->money = 0.0;
	F->num=0;
	F->tickets=0;
	F->next=NULL;
	return OK;
}
//创建航班结点
flightList creat_Flight(char *des,char *fid,char *pid,char *time,float money,int num,int tickets){
	flightList air;
	air = (Flight*)malloc(sizeof(Flight));
	if(NULL==air) return ERROR;
	strcpy(air->destination,des);
	strcpy(air->flightId,fid);
	strcpy(air->planeId,pid);
	strcpy(air->time,time);
	air->money = money;
	air->num = num;
	air->tickets = tickets;
	//air->clist = NULL;
	//init_waitQueue(air->wqueue);
	air->next = NULL;
	init_passengerList(air->CLientc); 
	init_waitQueue(air->wqueue);
	//air->Clientc->behind = NULL;
	//air->CLientc->head = NULL;
	return air;
}

//在航班总信息链表中插入新航班信息
Status insert_flight(Flight *&h, Flight *p)
{	Flight *f;
	f = h;
	if(NULL == f&&NULL == p) return ERROR;
	p->next = f->next;
	f->next = p;
	return OK;

} 

对乘客的操作

//初始化乘客链表 
Status init_passengerList(clientListL &CLient)
{
	CLient=(clientList *)malloc(sizeof(clientList));//创建头结点
	if(NULL==CLient) return OVERFLOW ;
	CLient->behind=NULL;
	CLient->head=NULL;
	return OK;
}

//创建乘客结点 
clientListL creat_client(char *name,char *ID_num,char *flight_num,char *time,int order_num,int amout,int rank){
	clientListL client;
	client = (clientList*)malloc(sizeof(clientList));
	if(NULL!=client) {
	
	strcpy(client->name,name);
	strcpy(client->ID_num,ID_num);
	strcpy(client->flight_num,flight_num);
	strcpy(client->time,time);

	client->order_num = order_num;
	client->amout = amout;
	client->rank = rank;
	//strcpy(client->rank,rank);
	client->behind = NULL;
	client->head = NULL;}
	//air->clist = NULL;
	//init_waitQueue(air->wqueue);
	return client;	
}
//在乘客链表中插入新结点 
Status insert_clientList(clientListL &totalList,clientListL &cp) {
	clientListL p;
	p = totalList->behind;

	if(cp==NULL) return ERROR;
	if(p==NULL) {
		totalList->behind = cp;
		cp->head = totalList;
	}
	else {
		while(p) {
			if(strcmp(p->name,cp->name)==1 ||strcmp(p->name,cp->name)==0) {
						if(p->head->head == NULL) {
							cp->head = totalList;
							cp->behind = p;
							totalList->behind = cp;
							p->head = cp;
							break;
						}
						else {
							cp->head = p->head;
							cp->behind = p;
							cp->head->behind = cp;
							p->head = cp;
							break; 
						}  }
			
			else{
			
				if(p->behind==NULL) {
					p->behind = cp;
					cp->head = p;
					break;
				}
			}
			p = p->behind;
		} 
	}

	return OK;
}

订票功能

//订票函数  
int booking(clientList *&airCLient,int amount,int sum,int order_num,char *name,char *ID_num,char *flightId,char *time){//把乘客的结点生成并接入乘客链表+接入航班结点里的乘客链表 

	clientListL pessage =  creat_client(name,ID_num,flightId,time,order_num,amount,sum);

		if(insert_clientList(airCLient,pessage) == OK){
		printf("购票成功");return OK;
}
    else {system("cls");
	printf("购票失败，钱款已退回，请联系工作人员购票");}
		}
		

//推荐路线函数		
void recommand(Flight *air,clientList *CLient,char *flightId,char *destination,int amount){
//根据目的地相同，航班号不同，推荐新的航班(有票时)//价格重新计算(机票数不变，舱位不变),也要生成订单号 
	int randx(); 
	flightList p;
	char name[MAXSIZE];//姓名
	char ID_num[MAXSIZE];

	 int order_num;//订单号
	 p = air->next;
	 int mark = 0;
	 if(NULL== p||NULL==air) {printf("没有航班信息");
	 return;}

					 float m = p->money;
					 printf("该票为%d等票,票价为%8.2f\n",rankx[j],m*(3.0/rankx[j]));
