操作使用链表实现，编译器使用vs2019
成员框架搭建: 用户进入操作界面，选择添加机票信息,包括(飞机航班号，出发地，目的地，起飞时间，降落时间，飞机票价，当日折扣，机票总数)
进入订票系统,输入起飞地，目的地，调用查询函数会打印机票信息到屏幕，若没有则告知，如果有，订票人开始订票。输入（姓名，身份证号，性别，订购航班，购票数量）

函数实现： 一.添加机票信息 将添加的机票信息文件写入内存中，之后的每次操作都在内存中进行

int Init(PLNode pstPlaneNodeHead, MANNode pstManNodeHead)//将文件的数据加载到内存中 { //先加载飞机机票信息 FILE* pfplane; //定义飞机机票文件指针 PlaneNode* pstPlaneNodeTemp, * pstPlaneNodeCur; pstPlaneNodeCur = pstPlaneNodeHead; pstPlaneNodeTemp = NULL; pfplane = fopen("plane.txt", "ab+"); if (pfplane == NULL) { printf("Can't open plane.txt!\n"); return -1; } else { //把文件数据读入链表中 while (!feof(pfplane)) { pstPlaneNodeTemp = (PlaneNode*)malloc(sizeof(PlaneNode)); //申请临时结点 if (fread(pstPlaneNodeTemp, sizeof(PlaneNode), 1, pfplane) == 1) { pstPlaneNodeTemp->next = NULL; pstPlaneNodeCur->next = pstPlaneNodeTemp; pstPlaneNodeCur = pstPlaneNodeTemp; } } free(pstPlaneNodeTemp); fclose(pfplane); } //2.再加载订票人信息 FILE* pfman; //定义文件指针 ManNode* pstManNodeTemp, * pstManNodeCur; pstManNodeCur = pstManNodeHead; pstManNodeTemp = NULL; pfman = fopen("man.txt", "ab+"); if (pfman == NULL) { printf("Can't open man.txt!\n"); return -1; } else { //把文件数据读入链表中 while (!feof(pfman)) { pstManNodeTemp = (ManNode*)malloc(sizeof(ManNode)); //申请临时结点 if (fread(pstManNodeTemp, sizeof(ManNode), 1, pfman) == 1) { pstManNodeTemp->next = NULL; pstManNodeCur->next = pstManNodeTemp; pstManNodeCur = pstManNodeTemp; } } free(pstManNodeTemp); fclose(pfman); } return 0; } void Insert(PLNode pstPlaneNodeHead)//添加机票信息 { PlaneNode* pstHead, * pstTail, * pstCur, * pstNew; char acFlight[10]; //保存航班号 pstHead = pstTail = pstPlaneNodeHead; //找尾巴 //让pstTail指向最后一个结点 while (pstTail->next != NULL) { pstTail = pstTail->next; } while (1) { printf("Input the new flight number(-1 to end):"); scanf("%s", acFlight); getchar(); if (strcmp(acFlight, "-1") == 0) { break; } //判断航班号是否重复 pstCur = pstPlaneNodeHead->next; while (pstCur != NULL) { if (strcmp(pstCur->data.acFlight, acFlight) == 0) { printf("this flight %s exists!\n", acFlight); return; } pstCur = pstCur->next; } //如果航班号没有和现有纪录重复，则新建一个链表结点 pstNew = (PlaneNode*)malloc(sizeof(PlaneNode)); strcpy(pstNew->data.acFlight, acFlight); printf("Input the Start City:"); scanf("%s", pstNew->data.acOrigin); printf("Input the Dest City:"); scanf("%s", pstNew->data.acDest); printf("Input the Departure time (Format 00:00):"); scanf("%s", pstNew->data.acTakeOffTime); printf("Input the Arrival time (Format 00:00):"); scanf("%s", pstNew->data.acReverveTime); printf("Input the price of ticket:"); scanf("%f", &pstNew->data.fPrice); printf("Input the discount of ticket(Format 0.0):"); scanf("%s", pstNew->data.acDiscount); printf("Input the number of tickets:"); scanf("%d", &pstNew->data.iNum); pstNew->next = NULL; pstTail -> next = pstNew; pstTail = pstNew; iSave = 1; //有新的航班信息，保存标志为1 } }

二.查询机票信息 选择航班号查询，目的地，出发地查询，可自行添加其他查询

void Search(PLNode pstPlaneNodeHead)//查询机票信息 { PlaneNode* pstPlaneNode; int Sel = 0; int count = 0; //计数器 char acFlight[10], acDes[10],acstart[10]; //航班号和目的地 pstPlaneNode = pstPlaneNodeHead->next; if (pstPlaneNode == NULL) { printf("is not have data"); return; } //按航班号查询 //按目的地查询 //按起始地查询 printf("Choose one way according to:\n1.flight number2.Dest3.Start\n"); scanf("%d", &Sel); if (Sel == 1) { //按航班号查询 printf("input the right flight number:"); scanf("%s", acFlight); PrintfHead(); //机票信息头部打印 while (pstPlaneNode != NULL) { if (strcmp(pstPlaneNode->data.acFlight, acFlight) == 0) { PrintData(pstPlaneNode); break; //航班号唯一 } else { pstPlaneNode = pstPlaneNode->next; } } //遍历结束，没有break，则没有用户记录 if (pstPlaneNode == NULL) { printf("Sorry,no record!\n"); return; } } else if (Sel == 2) { //按目的地查询 printf("input the right Dest:"); scanf("%s", acDes); PrintfHead(); //机票信息头部打印 while (pstPlaneNode != NULL) { if (strcmp(pstPlaneNode->data.acDest, acDes) == 0) { PrintData(pstPlaneNode); count++; } pstPlaneNode = pstPlaneNode->next; } //遍历结束，计数器为0，则没有记录 if (count ==0) { printf("Sorry,no record!\n"); return; } } else if (Sel == 3) { //按起始地查询 printf("input the right Start:"); scanf("%s", acstart); PrintfHead(); //机票信息头部打印 while (pstPlaneNode != NULL) { if (strcmp(pstPlaneNode->data.acOrigin, acstart) == 0) { PrintData(pstPlaneNode); count++; } pstPlaneNode = pstPlaneNode->next; } //遍历结束，计数器为0，则没有记录 if (count == 0) { printf("Sorry,no record!\n"); return; } } else { printf("Sorry,please input right number 1-3:\n"); return; } }

三.订票操作 思路：输入起始地和目的地，显示是否有票若有，多条航班(存入数据到结构体中)订票：输入订票人信息
订票：选择航班号

void Book(MANNode pstManNodeHead, PLNode pstPlaneNodeHead)//订票 { //思路：输入起始地和目的地，显示是否有票若有，多条航班(存入数据到结构体中) //订票：输入订票人信息 //订票：选择航班号 PlaneNode * pstPlaneNodeCur,*astPlane[10]; //保存数据临时结构体数组 ManNode* pstManNodeCur,*pstManNodeTemp=NULL; char acOrigin[10], acDest[10], acID[20], acName[20], acSex[10], acDescision[2], acFlight[10]; int iNum = 0, Record = 0, k = 0, flg = 0; //接受订票人信息头指针 pstManNodeCur=pstManNodeHead; while (pstManNodeCur->next != NULL) { pstManNodeCur = pstManNodeCur->next; }//将订票人结构体指向尾巴 //输入起始地和目的地 printf("input the start city:"); scanf("%s",acOrigin); printf("input the Dest city:"); scanf("%s",acDest); //查找起始地和目的地，存入临时结构体数组中 pstPlaneNodeCur = pstPlaneNodeHead->next; while (pstPlaneNodeCur != NULL) { if (strcmp(pstPlaneNodeCur->data.acOrigin,acOrigin) == 0&&strcmp(pstPlaneNodeCur->data.acDest,acDest) == 0) { astPlane[Record++] = pstPlaneNodeCur; } pstPlaneNodeCur = pstPlaneNodeCur->next; } //打印数据 printf("there are %d flights you can choose!\n",Record); PrintfHead(); for (k = 0; k < Record; k++) { PrintData(astPlane[k]); } if (Record == 0) { printf("Sorry,no flights you can book\*/\n"); } //订票 else { printf("do you want to book it?(y(Y))/n(N))\n"); scanf("%s", acDescision); getchar(); if (strcmp(acDescision, "y") == 0 || strcmp(acDescision, "Y") == 0) { printf("input your information!\n"); pstManNodeTemp = (ManNode*)malloc(sizeof(ManNode)); printf("input your name:"); scanf("%s", acName); strcpy(pstManNodeTemp->data.acName, acName); printf("input your id:"); scanf("%s", acID); strcpy(pstManNodeTemp->data.acID, acID); printf("input your sex(M/W):"); scanf("%s", acSex); strcpy(pstManNodeTemp->data.acSex, acSex); printf("input your want to book flight number:"); scanf("%s", acFlight); strcpy(pstManNodeTemp->data.acBookFilight,acFlight); for (k = 0; k < Record; k++) { if (strcmp(astPlane[k]->data.acFlight, acFlight) == 0) { if (astPlane[k]->data.iNum < 1) { printf("no ticket!"); return; } printf("remain%dtickets!\n", astPlane[k]->data.iNum); flg = 1; break; } } if (flg == 0) { printf("error\n"); return; }printf("Input the booknumber:"); scanf("%d", &iNum); //订购几张票 astPlane[k]->data.iNum = astPlane[k]->data.iNum - iNum; pstManNodeTemp->data.iBookNum = iNum; pstManNodeCur->next = pstManNodeTemp; pstManNodeTemp->next = NULL; pstManNodeCur = pstManNodeTemp; //可以不要 printf("success!\n"); iSave = 1; } } }

四.修改机票信息 为了方便，此处我并未创建新的子菜单，想要更加美观可以自行创建各个函数的子菜单页面

void Modify(PLNode pstPlaneNodeHead)//修改机票信息 { PlaneNode* pstPlaneNodeCur; char acFlight[10]; pstPlaneNodeCur = pstPlaneNodeHead->next; if (pstPlaneNodeCur == NULL) { printf("no flight to be modify!"); return; } else { printf("Input the flight number you want to modify!:"); scanf("%s", acFlight); while (pstPlaneNodeCur) { if (strcmp(pstPlaneNodeCur->data.acFlight, acFlight) == 0) { break; } else { pstPlaneNodeCur = pstPlaneNodeCur->next; } } if (pstPlaneNodeCur) { printf("input the new start city:"); scanf("%s", pstPlaneNodeCur->data.acOrigin); printf("input the new arrval city:"); scanf("%s", pstPlaneNodeCur->data.acDest); printf("input the new dicount:"); scanf("%s", pstPlaneNodeCur->data.acDiscount); printf("input the new acTakeOffTime:"); scanf("%s", pstPlaneNodeCur->data.acTakeOffTime); printf("input the new acReverveTime:"); scanf("%s", pstPlaneNodeCur->data.acReverveTime); printf("input the new fPrice:"); scanf("%f", &pstPlaneNodeCur->data.fPrice); printf("input the new iNum:"); scanf("%d", &pstPlaneNodeCur->data.iNum); printf("modify successful!\n"); iSave = 1; //此处可以封装一个函数，让这块代码不这么冗杂} } }

五.显示机票信息

void PrintfHead()//打印机票头部信息 { printf("|------------------------------------------------------------------------------|\n"); printf("|***********************************************************************|******|\n"); printf("|Flight|StartCity|DseCity|DepertureTime|ArrivalTime|***price***|Discount|number|\n"); printf("|******|*********|*******|*************|***********|***********|********|******|\n"); printf("|------------------------------------------------------------------------------|\n"); } void PrintData(PLNode pstPlaneNodeCur) { PlaneNode* pst = pstPlaneNodeCur; printf(" %3s%8s%8s%12s%12s%16f%7s%8d\n", pst->data.acFlight, pst->data.acOrigin, pst->data.acDest, pst->data.acTakeOffTime, pst->data.acReverveTime, pst->data.fPrice, pst->data.acDiscount, pst->data.iNum); } void Show(PLNode pstPlaneNodeHead)//显示所有机票信息 { PlaneNode* pstPlaneNodeCur = pstPlaneNodeHead->next; PrintfHead(); if (pstPlaneNodeHead->next == NULL) { printf("no flight ticket!\n"); } else { while (pstPlaneNodeCur != NULL) { PrintData(pstPlaneNodeCur); pstPlaneNodeCur = pstPlaneNodeCur->next; } } }

六.推荐机票信息 根据用户输入的出发地，目的地以及用户可以乘坐最早的时间（系统会给出这个时间后所有符合信息的机票信息）

void Recommed(PLNode pstPlaneNodeHead)//推荐机票信息 { PlaneNode* pstPlaneNodeCur; char acDest[10], acTime[10],acOrigin[10]; int iNum=0; pstPlaneNodeCur = pstPlaneNodeHead->next; printf("input your take city:"); scanf("%s", acOrigin); printf("input your destination city:"); scanf("%s", acDest); printf("input the earlist time you can take:"); scanf("%s", acTime); PrintfHead(); while (pstPlaneNodeCur != NULL) { if (strcmp(pstPlaneNodeCur->data.acOrigin, acOrigin) == 0 && strcmp(pstPlaneNodeCur->data.acDest, acDest) == 0&& strcmp(acTime, pstPlaneNodeCur->data.acTakeOffTime) < 0) { PrintData(pstPlaneNodeCur); iNum++; } pstPlaneNodeCur = pstPlaneNodeCur->next; } printf("there are %d flights you can choose!\n", iNum); if (iNum != 0) { printf("please choose 3rd operation to book it!\n"); } }

七.退票操作 输入订票人身份证号，显示相应的订票信息，选择退票

//找到id号相同的订票人记录，返回订票人节点 MANNode FindMan(MANNode pstManNodeHead, char acID[20]) { ManNode* pstManNodeCur = pstManNodeHead->next; while (pstManNodeCur) { if (strcmp(pstManNodeCur->data.acID, acID) == 0) { return pstManNodeCur; } pstManNodeCur = pstManNodeCur->next; } return NULL; } //找到订票人信息中的航班号记录，找到相应机票信息节点 PLNode FindPlane(PLNode pstPlaneNodeHead, char* acBookFlight) { PlaneNode* pstPlaneNodeCur = pstPlaneNodeHead->next; while (pstPlaneNodeCur) { if (strcmp(pstPlaneNodeCur->data.acFlight, acBookFlight) == 0) { return pstPlaneNodeCur; } pstPlaneNodeCur = pstPlaneNodeCur->next; } return NULL; } void Refund(MANNode pstManNodeHead, PLNode pstPlaneNodeHead)//退票 { ManNode* pstManNodeCur, * pstManNodeFind = NULL; PlaneNode* pstPlaneNodeFind = NULL; char acID[20],acdescison[2]; int iNum; //剩余票数 int iBooknum; //定了几个票 printf("input your id number :"); scanf("%s", acID); //找到订票人的结构体 pstManNodeFind = FindMan(pstManNodeHead, acID); if (pstManNodeFind == NULL) { printf("can't find!\n"); } else//退票 { printf("this is your tickets:\n"); printf("id number is :%s\n", pstManNodeFind->data.acID); printf("name is :%s\n", pstManNodeFind->data.acName); printf("sex is :%s\n", pstManNodeFind->data.acSex); printf("book flights :%s\n", pstManNodeFind->data.acBookFilight); printf("book number :%d\n", pstManNodeFind->data.iBookNum); printf("if you want to cancel it (y/n)?: "); scanf("%s", acdescison); if (strcmp(acdescison, "y") == 0 || strcmp(acdescison, "Y") == 0) { //找到前驱 pstManNodeCur = pstManNodeHead; while (pstManNodeCur->next != pstManNodeFind) { pstManNodeCur = pstManNodeCur->next; }//找到该订票人对应航班记录 pstPlaneNodeFind =FindPlane(pstPlaneNodeHead, pstManNodeFind->data.acBookFilight); //退票 if (pstPlaneNodeFind != NULL) { iNum = pstPlaneNodeFind->data.iNum; //机票剩余票数 iBooknum = pstManNodeFind->data.iBookNum; //订购人定票数 pstPlaneNodeFind->data.iNum = iNum + iBooknum; } //删除订票人节点 pstManNodeCur->next = pstManNodeFind->next; free(pstManNodeFind); printf("successful refund!\n"); iSave = 1; } } }

八.显示当前时间

void NowTime()//显示当前时间 { time_t It; It = time(NULL); printf("现在的时间是:%s ", ctime(&It)); }

九.保存机票信息，订票人信息 如果没有在操作界面选择保存信息，在退出系统时，主函数调用该函数，问用户是否选择保存刚刚录入内存的信息

void SaveMan(MANNode pstManNodeHead)//保存订票人信息 { FILE* pfMan; ManNode* pstManNodeCur; int count = 0; //保存多少条信息 int iflg = 1; //是否写入信息 pfMan = fopen("man.txt", "wb"); if (pfMan == NULL) { printf("the file can't be opened!"); return; } pstManNodeCur = pstManNodeHead->next; while (pstManNodeCur != NULL) { if (fwrite(pstManNodeCur, sizeof(ManNode), 1, pfMan) == 1) { pstManNodeCur = pstManNodeCur->next; count++; } else { iflg = 0; break; } } fclose(pfMan); } void SavePlane(PLNode pstPlaneNodeHead)//保存机票信息 { FILE* pfPlane; //机票文件信息 PlaneNode* pstPlaneNodeCur; int count = 0; //保存多少条信息 int iflg = 1; //是否写入信息 pfPlane = fopen("plane.txt", "wb"); if (pfPlane == NULL) { printf("the file can't be opened!"); return; } pstPlaneNodeCur = pstPlaneNodeHead->next; while (pstPlaneNodeCur != NULL) { if (fwrite(pstPlaneNodeCur,sizeof(PlaneNode) ,1, pfPlane)==1) { pstPlaneNodeCur = pstPlaneNodeCur->next; count++; } else { iflg = 0; break; } } if (iflg) { printf("you have save %d flights", count); iSave = 0; } fclose(pfPlane); }
