大家好,又见面了,我是你们的朋友全栈君。
用C语言解决飞机订票系统***
-
一、问题描述:
根据以下功能说明,设计航班信息、客户信息、订票信息的存储结构,设计程序完成相应功能。
*录入:* 可以录入航班情况(数据可以存储在一个数据文件中,数据个数不能少于8个、自行设计数据构成);客户信息(姓名,证件号,电话等);订票信息(订单要有编号,其余数据自行设计)。
****查询:****可以查询某个航线的情况(如,输入航班号,查询起降时间,起飞抵达城市,航班票价,票价折扣,确定航班是否满仓);可以输入起飞抵达城市,查询飞机航班情况;
****订票:****(订票情况可以存在一个数据文件中,结构自己设定)可以订票,如果该航班已经无票,可以提供相关可选择航班;
****退票:****可退票,退票后修改相关数据文件;
****修改航班信息:****当航班信息改变可以修改航班数据文件;
-
二、代码以及注意事项
1.注意事项:
提前将航班信息提前写入文档中,放到该代码文件夹中,在需要的时候读入文件就行。下图是我的文件夹:
- 注意:flight是提前要写好的航班信息文件
就比如这样:
而reserve文件在开始需为空,因为这是存储乘客信息的文件
就比如:
2、好了废话这莫多直接上代码:

三、总结
这是本人的第一篇博客,没办法谁让我还只是个弱鸡……
本人目前大二能力有限不过也已经在自学Python、也对一点点前端。
希望自己能在一个程序yuan的路上越走越远,加油hxd们!
