本文实例为大家分享了C语言实现火车订票系统的具体代码，供大家参考，具体内容如下
程序介绍1.运行程序时，首先进入到菜单部分，菜单部分提供了菜单显示和输入功能部分。其运行效果如图所示。在主界面上输入数字0——6，实现相应的功能。
2.主界面输入“1”，进入添加火车信息界面，如图所示。根据屏幕上给出的提示输入火车的车次，起点，终点，出发时间，到达时间，票价和可以订购的票数。
3.主界面输入“2”，可以查询火车信息，可以选择查询的方法有两种，一种是按照车次查询，一种是按照你想要到达的地方查询，运行效果如图所示。
4.当在主界面输入“3”时，进入订票界面，按照提示输入你想要到达的城市，会自动显示出你终点站为你输入城市的信息，根据提示输入你是否决定订票以及你的个人信息，运行效果如图所示。
5.当在主界面输入“4”时，进入修改界面，根据提示输入你要修改的内容，修改模块的运行效果如图所示。
6.当在主界面输入“5”时，可以显示出所有的火车信息，显示模块效果如图所示。
7.当在主界面输入“6”时，进入到保存模块，将录入的火车信息进行保存，并且将订票人的信息也进行保存，存储在指定的磁盘文件中。运行效果如图所示。
