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：******-12苏龙  学号***********\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;

case 5: output();

break;

case 0: exit();

}

printf("\n\n操作完毕，请再次选择！");

}

else

printf("\n\n选择错误，请再次选择！");

}

}

2 数据添加

【程序】

void append()                          

{

if((fp=fopen("worker.xls

{

printf("\n不能打开该文件！");

exit();

}

printf("\n请输入添加职工信息(姓名、职工号、性别、年龄、学历、职位、工资、电话、地址)\n");

scanf("%s%s%s%s%s%s%s%s%s",one.name,one.num,one.sex,one.age,one.record,one.position,one.wanges,one.tel,one.addr);

fprintf(fp,"%-10s%-8s%-5s%-5s%-10s%-8s%-8s%-10s%-15s\n",one.name,one.num,one.sex,one.age,one.record,one.position,one.wanges,one.tel,one.addr);

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！
