C语言实现火车订票系统
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。
