这个项目是我今年的C语言课设。做这个项目一个人大概用了一天的时间来完成,整体将近700行,量不是很多,所以也没用多文件什么的,当然也是采用了模块化设计的思路,在代码中写了几个函数来实现特定的功能。
以下是这个项目的一些要求和全部源码。
一、软件开发目的
该软件主要是使用C语言设计开发一个简单的车辆租赁管理系统,实现租赁信息的查询、修改、删除、添加以及订单的查询等功能。
二、数据结构
程序中采用结构体数组存储租赁信息。租赁结构体成员包括:订单号、身份证号、车牌号、费用。数组的长度不超过100。
三、软件功能说明
1.租赁信息的录入和保存:
输入租赁信息包括:订单号、身份证号、车牌号、费用。还车前费用为0。在录入数据的同时,系统将对信息的合法性进行检验,若录入了不合法的数据系统应作出提示,并且要求重新输入。
2.显示单条租赁信息:
将租赁信息在屏幕上列表输出。要求先显示提示信息“订单号、身份证号、车牌号、费用”,然后再显示租赁信息,每行显示一条租赁信息。
3.查询单条租赁信息
输入身份证号进行查询,输出符合条件的租赁信息,输出订单号、身份证号、车牌号、费用。
4.查询每辆车的租赁费用:
输入车牌号进行查询,输出该车所有租赁的总费用。输出车牌号、总费用。
5.添加租赁信息
输入新的租赁信息,将新的信息插入原租赁信息清单中,并将新的列表输出,以方便用户确认。
6.修改、删除租赁信息
通过身份证号对某条租赁信息进行进行修改和删除,并将租赁信息列表输出,以方便用户确认。
7.统计:
(1)统计输出当月订单总金额
(2)统计输出订单金额最高的车牌号
8.退出系统,结束任务。
