c语言课程设计---职工信息管理系统(共7页).doc
精选优质文档-倾情为你奉上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、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 <stdio.h>#include <string.h>#include <stdlib.h>typedef struct Empk int EmpNum; /* staff number */ char EmpName12; /* name*/ int Sex; /*sex 1- woman 2- man*/ int Old; /* old*/ int Cult; /*education background 1-specilist 2-doctor 3-others*/ int Salary; /*salary*/ char Address12; /* address*/ int Tell; /*telephone number*/Emp;Emp emp100;void open() int i; FILE *fp; if(fp=fopen("wyl","rb+")=NULL) printf("can not do it!
