1、 C 语言课程设计 设计题目：职工信息管理系统 设计目的 当今时代是飞速发展的信息时代，在各行各业中离不开信息处理，这正是计算机被广泛应用于信息系统的环境。计算机的最到好处的于利用它能够进行信息管理，使用计算机进行信息控制，不仅提高了工作效率，而且大大的提高了其安全性。尤其对于复杂的信息管理，计算机能够充分发挥它的优越性。计算机进行信息管理与信息管理系统的开发密切相关，系统的开发是系统管理的前提。本系统就是为了管理好学生选课信息而设计的。数据处理手工操作，工作量大，出错率高，出错后不易更改，造成了时间上的浪费。基于这个问题，我认为有必要建立一个学生选课系统，使学生选课信息管理工作规范化、系统化
2、、程序化，避免学生选课管理的随意性，提高信息处理的速度和准确性，能够及时、准确、有效的查询和修改选课情况。二、题目说明：系统功能简介：系统以菜单方式工作 1）职工信息录入（文件保存职工信息）2）输出职工信息、浏览职工信息 3）查询职工信息 4）根据员工号查找职工信息 5）根据工资、年龄、性别对职工信息进行排序 6）删除职工信息 3.设计实施：#include#include#include typedef struct Empk int EmpNum;/*staff number*/char EmpName12;/*name*/int Sex;/*sex 1-woman 2-man*/int
