课程设计报告
一 C语言课程设计的目的
设计一职工信息管理系统，使之能提供以下功能：
（1） 系统以菜单方式工作
（2） 职工信息录入功能（职工信息用文件保存）
（3） 职工信息浏览功能
（4） 职工信息查询功能，查询方式可按学历查询或按职工号查询
（5） 职工信息删除修改功能（可选项）
二 课程设计报告正文
1题目要求
设计职工信息管理系统，要求职工心想包括职工号、姓名、性别、年龄、学历、工资、住址、电话等（职工号不重复）。设计一职工信息管理系统，使之能提供以下功能：
（6） 系统以菜单方式工作
（7） 职工信息录入功能（职工信息用文件保存）
（8） 职工信息浏览功能
（9） 职工信息查询功能，查询方式可按学历查询或按职工号查询
（10） 职工信息删除修改功能（可选项）
2需求分析
根据题目要求，由于职工信息是存放在文件中，所以应提供文件的输入、输出等操作；在程序中需要浏览职工的信息，应提供显示、查找、排序等操作；另外还应提供键盘式选择菜单实现功能选择。
3总体设计
根据上面的需求分析,可以将这个系统设计分为以下模块：数据添加、数据查找、数据修改、数据删除、数据输出。系统功能模块如下：
4详细设计
1 主函数
主函数设计要简洁，只提供部分函数的调用。其中各功能模块用菜单方式选择。
【程序】
void main()
{
int m;
while(1)
{ printf("\n\n\n\t\t ______________________________________\n");
printf("\t\t 欢迎进入中国地质大学(武汉)员工信息系统\n");
printf("\t\t 设计者：055071-12苏龙 学号20071001569\n");
printf("\t\t ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\n");
printf("\n\t\t\t\t添加，请按1");
printf("\n\t\t\t\t查找，请按2");
printf("\n\t\t\t\t修改，请按3");
printf("\n\t\t\t\t删除，请按4");
printf("\n\t\t\t\t输出，请按5");
printf("\n\t\t\t\t退出，请按0\n");
scanf("%d",&m);
if(m>=0&&m<=5)
{
switch(m)
{
case 1: append();
break;
case 2: search();
break;
case 3: modify();
break;
case 4: delete();
break;

5运行与测试报告：
三 后记/课程设计过程中遇到的问题以及解决方法，课程设计的体会。
这次课程设计让我掌握了许多的有用知识。首先我能够熟练的应用软件Microsoft Visual C++ 6.0 了。再就是我能够根据自己的需要设计程序，这将对我以后的生活有非常重要的影响。同时我掌握了解决问题的方法，这无论是对以后的学习、生活都有无比重要的价值。
在设计中，我遇到了不少的困难，比如不能清晰的建立设计模块，然后我向同学寻求帮助，向他们学习，最终通过自己努力建立了模块。还有就是起初我设计的程序总是有错误，我细心的修改，不断的改进，最终我做出了自己非常理想的程序！
