一、题目
汽车租赁信息管理系统
对某汽车租赁公司汽车租赁信息进行管理，包括汽车基本信息和汽车租赁信息。
（1）需要处理的基础数据
a) 汽车租赁公司信息参考：
b) 汽车基本信息参考：
c) 汽车租赁信息参考：
（2）系统功能
a) 各种基本数据的录入。如：汽车基本信息录入、租赁公司信息录入、汽车租赁信息录入。
b) 各种基本数据的修改。即：允许对已经录入的数据重新进行编辑、修改。
c) 各种基本数据的插入。
d) 各种基本数据的删除。
e) 基于各种数据的查询。如：某租赁公司在指定日期的租车信息。
f) 基于各种基本数据的统计计算。如：
（I）统计各汽车租赁公司总汽车数和租金总额，按租金总额从高到低排序后输出。 （II）统计某年度十二个月份汽车租赁的总次数和总租金。
（III）统计各公司各类汽车出租次数、出租金额，按出租金额从高到低排序后输出。
（IV）分别统计出租率最高的5家公司，从高到低排序后输出公司名称、公司汽车总数、出租总次数。
（V）汽车租赁信息其它方面的统计。
二、系统功能模块结构图
三、数据结构设计及用法说明
这个系统是采用三个方向的十字链表，其中第一条链是汽车租赁公司的基本信息，包括公司名称、汽车类型和各类型汽车数量，第二条链是汽车基本信息，包括汽车类型、公司名称、汽车数、日租金、联系人和联系电话，第三条链是汽车租赁的基本信息，包括客户姓名、身份证号、租车日期、租车天数、公司名称、汽车类型和租车数目。
下图就是数据三个方向的十字交叉链表
四、程序结构
下图为程序结构的流程图：
五、各模块的功能
Build :Load:将已经存好的数据导入
New：输入新的数据
Save：将输入的数据保存
Quit:退出程序
Search:Firm:查询公司信息
Bus:查询汽车信息
Busrent查询汽车租赁信息
Modify:Firm:修改公司信息
Bus:修改汽车信息
Busrent:修改汽车租赁信息
Delete:Firm:删除公司信息
Bus:删除汽车信息
Busrent:删除汽车租赁信息
Insert:Firm:插入公司信息
Bus:插入汽车信息
Busrent:插入汽车租赁信息
Output:Firm:输出公司信息
Bus:输出汽车信息
Busrent:输出汽车租赁信息
Censue:Tongji1:统计每个公司的汽车总数和租赁的总收入
Tongji2:统计每个年度所有公司出租汽车总数和总收入 Tongji3:统计每个公司每种类型的汽车出租次数和收入
Tongji4:统计每个公司汽车的出租率、总汽车数和租出汽车次数 Tongji5:统计所有公司的所有年度汽车出租总数和总收入
六、试验结果
七、体会
这次实验结合了C语言里面的数组、指针、链表、文件等知识点。刚开始的时候不知道如何下手，后来在相关书籍上找了相似的程序慢慢分析后开始自己尝试着写，因为开始的时候还是不会，就和寝室里面的人讨论、相互参考，经过几天的研究，我们终于写出了第一个界面，有了第一次的经验，我慢慢的写出了Build函数以及后面的函数。最难的就是函数的调试了，开始运行的时候报错特别多，自己就那样一点一点的调，错误也渐渐减少，但是到最后又几个错误不管我怎么调就是报错，当时真的很着急，后来找到了班上成绩比较好的同学，纵欲把最后几个报错的地方改正了。经过这么多的曲折，当我看到自己写出来的程序时心里有的是高兴与激动。或许对于别人来说，这次的实验只是小菜一碟，但对我来说，这是经过我的付出与努力换来的。
