c语言人事管理系统

一、内容（标题：宋体，粗体，四号字）
本程序主要实现了对高校人事的管理。

其不仅可以对人员的新建、添加、删除的基本操作，还可以进行查询编辑、以不同的方式排序等操作。

进行操作时，只要输入相对应的数字或信息即可。

二、上机环境
操作系统：win 7\.windows Xp
开发工具：VC6.0
三、函数调用关系图
四、各函数功能说明
1. void add(); 新建\添加
2. void del(); 删除
3. void sear_edit(); 查询编辑
4. void scan(); 浏览
5. void order(); 排序
6. void old_order(); 年龄排序
7. void comingtime_order(); 来院时间排序
8. void main() 主函数
五、算法描述或流程图
0.main ( )函数
1.add ( )函数
2.del （）函数
3.sear_edit( )函数
4.scan （）函数
5.order ( )函数
6.exit （）函数
六、程序运行效果图
0.main （）函数
1.添加函数exit （）exit （）退出
2.浏览
3.查询编辑
4.删除
5.排序
6.删后浏览
七、总结
一星期的C语言课程设计结束了，在这八天的时间里，我自己独立完成了一个程序从构思结构，到编写代码，然后上机调试运行的过程，感觉自己收获很大。

通过解决一个又一个的问题，熟悉了C语言的应用，对计算机语言应用的理解又深了一层，在老师的指导下，学会了模块设计的方法，用流程图表示算法，掌握了用C语言进行程序设计的能力。

在设计过程中，我理解了对于一个较大的程序，不可能一次编写出一个较大的系统，通常要采取自顶向下的设计思想，先设计主函数，再通过完善一个个的功能模块来完成程序的设计过程，在设计过程中要充分理解整个程序的设计思路，采用逐步细化的方式来完成整个程序。

使各个模块能够很好地兼容在一起，并进行运行测试，程序能够无错误的运行。

之后，优化界面和显示，使人能够轻松愉悦地操作。

在在运行调试过程中，当删除或更改了信息后可进行查询操作但就不能进行浏览，可是，在文本文件中删除最后一个空格，程序就能正确无误地运行。

在这问题中，我用过在文件尾加\b等的方法，还是解决不了，最后，我想到在文件写入时先\n，再写入，这样一来，文件末的空格就不存在了，经运行测试证明，问题就此解决。

这次课程设计给我最大的启示就是解决问题要多看多思考，同时，设计并完善这个简单的程序竟然花了我这么长时间，也说明平时用功还不够，以后得加倍努力！
