这篇具有很好参考价值的文章主要介绍了C语言阶段小项目（火车购票系统）。希望对大家有所帮助。如果存在错误或未考虑完全的地方，请大家不吝赐教，您也可以点击"举报违法"按钮提交疑问。

铁路售票管理系统
程序中传递的有信息有：票务信息（包括车次，出发站、到达站、出发时间日期，历时、票数,票价）个人购票信息(姓名，身份信息，车次，出发时间日期，座位号，票价)

票务浏览（对票务系统中的所有票务信息进行浏览，获取不同时间日期的票务信息。）
购票当乘客购票成功后，为乘客构建购票信息，用于存储该乘客所有的购票信息，
以便乘客查询，同时减少票务系统中的相关票数。
退票当乘客退票成功后，将相关的购票信息从为乘客构建的购票信息系统中删除，
同时增加票务系统中的相关票数。
信息查看乘客可随时查看票务系统中所有的票务信息，同时也可提供UI，用于查看个人的所有购票信息。
