C语言如何实现单位车辆调度管理

本篇内容主要讲解“C语言如何实现单位车辆调度管理”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“C语言如何实现单位车辆调度管理”吧!

单位车辆信息包括：车牌号、车型、载重（客）量，车牌，生产厂家，出厂日期，购买日期，购买单价等；车辆调度信息还应包括：用车人，用车单位，调度人，出车车牌，出车司机，出车用途，出车日期，出车时间，收车日期，收车时间及出车费用等信息等。设计“车辆调度管理系统”，使之能提供以下功能：

系统以菜单方式工作；

车辆调度信息录入功能(车辆调度信息用文件vehicle.txt保存)；

车辆信息及车辆调度信息浏览功能；

车辆调度查询和排序功能： 

车辆信息及车辆调度信息的删除与修改等功能。

代码如下，完全原创，代码功能完整！！
