C語言實(shí)現(xiàn)飛機(jī)訂票系統(tǒng)的完整代碼

 更新時(shí)間：2022年06月15日 11:30:31   作者：編程小程  
為了免去在窗口排隊(duì)買票的麻煩,飛機(jī)訂票系統(tǒng)應(yīng)運(yùn)而生,下面這篇文章主要給大家介紹了關(guān)于C語言實(shí)現(xiàn)飛機(jī)訂票系統(tǒng)的相關(guān)資料,文中通過實(shí)例代碼介紹的非常詳細(xì),需要的朋友可以參考下

題目

本文將設(shè)計(jì)一個(gè)飛機(jī)訂票系統(tǒng)，主要包括機(jī)票的添加、修改、查找、訂票、退票、推薦機(jī)票功能，用C語言編程實(shí)現(xiàn)，并用鏈表存儲產(chǎn)生的航班信息和訂票信息數(shù)據(jù)，最后可以把鏈表中的數(shù)據(jù)保存到文件中。

總體設(shè)計(jì)和需求分析

設(shè)計(jì)目的

1.怎樣去合理的設(shè)計(jì)一個(gè)數(shù)據(jù)結(jié)構(gòu)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(xué)習(xí)和理解

3.學(xué)習(xí)如何鏈表和外部文件之間的讀取和存儲操作

4.學(xué)習(xí)如何將學(xué)到的知識應(yīng)用到實(shí)際的問題中

總體設(shè)計(jì)和功能

此飛機(jī)訂票系統(tǒng)將實(shí)現(xiàn)以下功能：
 

1.初始化功能

  該功能將實(shí)現(xiàn)將航班信息文件和訂票人訂票信息文件中的數(shù)據(jù)讀取到鏈表中。

2.添加機(jī)票信息功能

  該功能將實(shí)現(xiàn)添加航班機(jī)票信息，信息包括航班號、出發(fā)地、目的地、起飛時(shí)間、降落時(shí)間、票價(jià)、折扣、剩余票數(shù)，然后用鏈表將數(shù)據(jù)保存起來。

3.查詢機(jī)票信息功能

  該功能將實(shí)現(xiàn)通過航班號來查詢機(jī)票信息的功能

4.修改機(jī)票信息功能

  該功能將通過航班號調(diào)用查找機(jī)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(xiàng)航班信息。

5.顯示機(jī)票信息

  該功能將實(shí)現(xiàn)把所有航班信息顯示出來

7.推薦機(jī)票功能

  該功能將實(shí)現(xiàn)通過輸入目的地，和乘客最早出發(fā)時(shí)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(shù)量、訂購航班號以實(shí)現(xiàn)用戶訂票功能

9.退票功能

  該功能下乘客可以訂購的機(jī)票進(jìn)行退回。

10.顯示時(shí)間功能

  該功能可以顯示實(shí)時(shí)時(shí)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。

結(jié)構(gòu)體設(shè)計(jì)

我們將定義兩個(gè)結(jié)構(gòu)體，分別為機(jī)票信息結(jié)構(gòu)體和訂票人信息結(jié)構(gòu)體

機(jī)票信息結(jié)構(gòu)體

typedef struct AirPlane
{
	char acFlight[20];//航班號
	char acOrigin[10]; //出發(fā)地
	char acDest[20];  //目的地
	char acTakeOffTime[10]; //起飛時(shí)間
	char acReverceTime[10]; //降落時(shí)間
	float fPrice;  //票價(jià)
	char acDisscount[4];  //折扣
	int iNum;  //剩余票數(shù)
}AirPlane, * PAirPlane;
//定義機(jī)票信息節(jié)點(diǎn)的結(jié)構(gòu)體
typedef struct PlaneNode
{
	struct AirPlane stDate;
	struct PlaneNode* pstNext;

}PlaneNode, * PPlaneNode;

訂票人信息結(jié)構(gòu)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(shù)量
	char acBookFilght[10];  //訂購航班號
}Man, * PMan;
//訂票人信息節(jié)點(diǎn)的結(jié)構(gòu)體
typedef struct ManNode
{
	struct Man stDate;
	struct ManNode* pstNext;
}ManNode, * PManNode;

主函數(shù)的設(shè)計(jì)

在主函數(shù)中，首先將通過初始化函數(shù)把文件中的數(shù)據(jù)讀取到鏈表中，然后可以通過switch選擇用戶在飛機(jī)訂票系統(tǒng)中需要執(zhí)行的操作

//作為數(shù)據(jù)改動(dòng)的標(biāo)志
int iSave = 0;

int main()
{
	struct PlaneNode pstPlaneNodeHead;  //機(jī)票信息頭結(jié)點(diǎn)
	pstPlaneNodeHead.pstNext = NULL;
	struct ManNode pstManNodeHead;    //購票信息頭結(jié)點(diǎn)
	pstManNodeHead.pstNext = NULL;

	Init(&pstPlaneNodeHead, &pstManNodeHead);  // 將文件的數(shù)據(jù)加載到內(nèi)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(jìn)入添加機(jī)票頁面\n");
			Insert(&pstPlaneNodeHead); // 添加機(jī)票信息
			break;
		case 2:
			Search(&pstPlaneNodeHead);   //查詢機(jī)票信息
			break;
		case 3:
			Book(&pstPlaneNodeHead, &pstManNodeHead);//訂票
			break;
		case 4:
			Modify(&pstPlaneNodeHead);    //修改機(jī)票信息
			break;
		case 5:
			Show(&pstPlaneNodeHead);   //顯示機(jī)票信息  
			break;
		case 6:
			Recommend(&pstPlaneNodeHead);  //推薦機(jī)票信息
			break;
		case 7:
			Refund(&pstPlaneNodeHead, &pstManNodeHead);//退票信息
			break;
		case 8:
			NowTime();//顯示當(dāng)前時(shí)間
			break;
		case 9:
			SaveMan(&pstManNodeHead);     //數(shù)據(jù)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(jī)票信息

				}
			}
			Destroy(&pstPlaneNodeHead, &pstManNodeHead);
			return 0;
		}
		printf("\nplease press any key to continue...\n");
		_getch();
	}
	Destroy(&pstPlaneNodeHead, &pstManNodeHead);
	return 0;
}

測試

先進(jìn)行添加機(jī)票功能的測試

![在這里插入圖片描述](https://img-blog.csdnimg.cn/7d5bcf3869d14bd5a8e6e8c157474d03.png?x-oss-process=image/watermark,type_d3F5LXplbmhlaQ,shadow_50,text_Q1NETiBA57yW56iL5bCP56iL,size_20,color_FFFFFF,t_70,g_se,x_16

將添加機(jī)票信息輸入完整，然后輸入-1返回主菜單

然后對查詢機(jī)票功能進(jìn)行測試，輸入剛剛添加的航班號，可以看出已經(jīng)查詢到新添加的機(jī)票信息

然后對修改機(jī)票信息功能進(jìn)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(jī)票信息的功能

可以看出已經(jīng)成功把1005號航班的目的地修改為beijing

對推薦機(jī)票功能進(jìn)行測試

選擇你要去的地方和你最早可以到達(dá)時(shí)間，然后會打印符合條件的機(jī)票信息

然后對訂票功能進(jìn)行測試

然后對退票功能進(jìn)行測試，通過ID可以定位到剛剛訂票的信息，然后選擇退票
