c語言課程設計---職工信息管理系統

1、精選優(yōu)質文檔-傾情為你奉上精選優(yōu)質文檔-傾情為你奉上專心-專注-專業(yè)專心-專注-專業(yè)精選優(yōu)質文檔-傾情為你奉上專心-專注-專業(yè)C語言課程設計設計題目：職工信息管理系統設計目的當今時代是飛速發(fā)展的信息時代，在各行各業(yè)中離不開信息處理，這正是計算機被廣泛應用于信息系統的環(huán)境。計算機的最到好處的于利用它能夠進行信息管理，使用計算機進行信息控制，不僅提高了工作效率，而且大大的提高了其安全性。尤其對于復雜的信息管理，計算機能夠充分發(fā)揮它的優(yōu)越性。計算機進行信息管理與信息管理系統的開發(fā)密切相關，系統的開發(fā)是系統管理的前提。本系統就是為了管理好學生選課信息而設計的。數據處理手工操作，工作量大，出錯率高，出錯

2、后不易更改，造成了時間上的浪費?；谶@個問題，我認為有必要建立一個學生選課系統，使學生選課信息管理工作規(guī)范化、系統化、程序化，避免學生選課管理的隨意性，提高信息處理的速度和準確性，能夠及時、準確、有效的查詢和修改選課情況。二、題目說明： 系統功能簡介：系統以菜單方式工作職工信息錄入（文件保存職工信息）輸出職工信息、瀏覽職工信息查詢職工信息根據員工號查找職工信息根據工資、年齡、性別對職工信息進行排序刪除職工信息3. 設計實施：#include #include #include typedef struct Empk int EmpNum; /* staff number */ char Emp
