C语言课程设计 职工信息管理系统

1、青岛理工大学C语言程序实习题目 职工信息管理系统 指导教师： 姓名： 学号： 班级： 专业： 地点： 时间： 一、职工信息管理系统本系统主要功能是实现职工信息的管理，主要有三个功能：1、建立职工信息2、查询职工信息；3、修改职工信息。4.输出职工信息二、上机环境：操作系统：windowsXP开发工具：VC6.0三、函数调用关系：main函数stablishaltersearchoutput四、各函数功能说明 1.main()函数： 主函数 ，通过调用各个函数实现职工信息管理2.creat()函数 ： 新建职工信息3.search()函数 ： 按编号查询某员工信息4.alter()函数： 修改员

2、工信息5.output()函数 ： 按文件名输出员工信息五、各个函数算法描述或流程图stablish开始switchaltersearchoutput结束六、程序运行效果图1运行主界面2、建立文件界面3.职工信息查询界面4.输出信息七、体会在本学期学习中，通过学习C程序设计课，我懂得了C语言是计算机语言的基础，必须学好它，才能更进一步的发展自己，我现在只是初学者，还有很多的不足，需要改正和完善。在以后的学习中我会更加端正我的学习态度，认真学好每一个细节，努力学好这门课程。此次所编程序尚有很多漏洞，有待完善。八、参考文献1 谭浩强 .C程序设计(第三版).清华大学出版社,2005 2 谭浩强 .
