這篇文章主要介紹了如何使用C語(yǔ)言實(shí)現(xiàn)飛機(jī)訂票系統(tǒng)的相關(guān)知識(shí)，內(nèi)容詳細(xì)易懂，操作簡(jiǎn)單快捷，具有一定借鑒價(jià)值，相信大家閱讀完這篇如何使用C語(yǔ)言實(shí)現(xiàn)飛機(jī)訂票系統(tǒng)文章都會(huì)有所收獲，下面我們一起來(lái)看看吧。
1.怎樣去合理的設(shè)計(jì)一個(gè)數(shù)據(jù)結(jié)構(gòu)來(lái)存儲(chǔ)訂票信息和航班信息
2.加深對(duì)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(chǔ)操作
4.學(xué)習(xí)如何將學(xué)到的知識(shí)應(yīng)用到實(shí)際的問(wèn)題中
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(hào)、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(lái)。
3.查詢機(jī)票信息功能
  該功能將實(shí)現(xiàn)通過(guò)航班號(hào)來(lái)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(guò)航班號(hào)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(guò)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(lái)
7.推薦機(jī)票功能
  該功能將實(shí)現(xiàn)通過(guò)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(hào)碼、性別、購(gòu)票數(shù)量、訂購(gòu)航班號(hào)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(gòu)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。
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

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

}先進(jìn)行添加機(jī)票功能的測(cè)試
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(duì)查詢機(jī)票功能進(jìn)行測(cè)試，輸入剛剛添加的航班號(hào)，可以看出已經(jīng)查詢到新添加的機(jī)票信息
然后對(duì)修改機(jī)票信息功能進(jìn)行測(cè)試，我們將目的地修改為beijing
然后返回主菜單，測(cè)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(hào)航班的目的地修改為beijing
對(duì)推薦機(jī)票功能進(jìn)行測(cè)試
選擇你要去的地方和你最早可以到達(dá)時(shí)間，然后會(huì)打印符合條件的機(jī)票信息
然后對(duì)訂票功能進(jìn)行測(cè)試
然后對(duì)退票功能進(jìn)行測(cè)試，通過(guò)ID可以定位到剛剛訂票的信息，然后選擇退票
