這篇文章主要介紹了如何使用C語言實現飛機訂票系統的相關知識，內容詳細易懂，操作簡單快捷，具有一定借鑒價值，相信大家閱讀完這篇如何使用C語言實現飛機訂票系統文章都會有所收獲，下面我們一起來看看吧。
1.怎樣去合理的設計一個數據結構來存儲訂票信息和航班信息
2.加深對鏈表的增刪改查功能的學習和理解
3.學習如何鏈表和外部文件之間的讀取和存儲操作
4.學習如何將學到的知識應用到實際的問題中
此飛機訂票系統將實現以下功能：
1.初始化功能
  該功能將實現將航班信息文件和訂票人訂票信息文件中的數據讀取到鏈表中。
2.添加機票信息功能
  該功能將實現添加航班機票信息，信息包括航班號、出發地、目的地、起飛時間、降落時間、票價、折扣、剩余票數，然后用鏈表將數據保存起來。
3.查詢機票信息功能
  該功能將實現通過航班號來查詢機票信息的功能
4.修改機票信息功能
  該功能將通過航班號調用查找機票信息功能，定位到要修改的航班信息上，然后通過航班信息子菜單確定要修改的某一項航班信息。
5.顯示機票信息
  該功能將實現把所有航班信息顯示出來
7.推薦機票功能
  該功能將實現通過輸入目的地，和乘客最早出發時間可以獲得符合條件的航班信息
8.訂票功能
  該功能下乘客輸入目的地，并且輸入訂票人的姓名、身份證號碼、性別、購票數量、訂購航班號以實現用戶訂票功能
9.退票功能
  該功能下乘客可以訂購的機票進行退回。
10.顯示時間功能
  該功能可以顯示實時時間
11.保存信息功能
該功能下可以把鏈表中的信息保存到文件中。
我們將定義兩個結構體，分別為機票信息結構體和訂票人信息結構體
typedef struct AirPlane
{
char acFlight[20];//航班號
char acOrigin[10]; //出發地
char acDest[20]; //目的地
char acTakeOffTime[10]; //起飛時間
char acReverceTime[10]; //降落時間
float fPrice; //票價
char acDisscount[4]; //折扣
int iNum; //剩余票數
}AirPlane, * PAirPlane;
//定義機票信息節點的結構體
typedef struct PlaneNode
{
struct AirPlane stDate;
struct PlaneNode* pstNext;
}PlaneNode, * PPlaneNode;訂票人信息結構體
typedef struct Man
{
char acName[20]; //姓名
char acID[20]; //身份證號碼
char acSex[10]; //性別
int iBookNum; //購票數量
char acBookFilght[10]; //訂購航班號
}Man, * PMan;
//訂票人信息節點的結構體
typedef struct ManNode
{
struct Man stDate;
struct ManNode* pstNext;
}ManNode, * PManNode;在主函數中，首先將通過初始化函數把文件中的數據讀取到鏈表中，然后可以通過switch選擇用戶在飛機訂票系統中需要執行的操作
//作為數據改動的標志
int iSave = 0;
int main()
{
struct PlaneNode pstPlaneNodeHead; //機票信息頭結點
pstPlaneNodeHead.pstNext = NULL;
struct ManNode pstManNodeHead; //購票信息頭結點
pstManNodeHead.pstNext = NULL;
Init(&pstPlaneNodeHead, &pstManNodeHead); // 將文件的數據加載到內存中
int iSel = 0; //用于接收用戶對功能的選擇
char c1;
while (1)
{
system("cls");
Menu();
printf("Input 0-9 operations:");
scanf_s("%d", &iSel);
getchar();
switch (iSel)
{
case 1:
printf("進入添加機票頁面\n");
Insert(&pstPlaneNodeHead); // 添加機票信息
break;
case 2:
Search(&pstPlaneNodeHead); //查詢機票信息
break;
case 3:
Book(&pstPlaneNodeHead, &pstManNodeHead);//訂票
break;
case 4:
Modify(&pstPlaneNodeHead); //修改機票信息
break;
case 5:
Show(&pstPlaneNodeHead); //顯示機票信息
break;
case 6:
Recommend(&pstPlaneNodeHead); //推薦機票信息
break;
case 7:
Refund(&pstPlaneNodeHead, &pstManNodeHead);//退票信息
break;
case 8:
NowTime();//顯示當前時間
break;
case 9:
SaveMan(&pstManNodeHead); //數據保存
SavePlane(&pstPlaneNodeHead);
break;
case 0:
if (iSave == 1)
{
printf("do you want to save (y/n)");
scanf("%c", &c1);
getchar();
if (c1 == 'y' || c1 == 'Y')
{
SaveMan(&pstManNodeHead); //保存訂票人的信息
SavePlane(&pstPlaneNodeHead); // 保存機票信息
}
}
Destroy(&pstPlaneNodeHead, &pstManNodeHead);
return 0;
}
printf("\nplease press any key to continue...\n");
_getch();
}
Destroy(&pstPlaneNodeHead, &pstManNodeHead);
return 0;

}先進行添加機票功能的測試
將添加機票信息輸入完整，然后輸入-1返回主菜單
然后對查詢機票功能進行測試，輸入剛剛添加的航班號，可以看出已經查詢到新添加的機票信息
然后對修改機票信息功能進行測試，我們將目的地修改為beijing
然后返回主菜單，測試顯示所有機票信息的功能
可以看出已經成功把1005號航班的目的地修改為beijing
對推薦機票功能進行測試
選擇你要去的地方和你最早可以到達時間，然后會打印符合條件的機票信息
然后對訂票功能進行測試
然后對退票功能進行測試，通過ID可以定位到剛剛訂票的信息，然后選擇退票
