一、問題描述及要求

設計題目	?員工信息管理系統	成績	?
課 程 設 計 主 要 內 容	【問題描述】 編寫一個程序來管理員工信息。通過一個類來存放輸入的每一位員工的記錄(包括員工號、姓名、性別、所屬部門、職稱、入職時間、聯系電話等),然后將其信息保存到文件中。通過幾個函數來創建新員工號,并對職工信息進行刪除及修改,輸入一個員工號查詢該職工的信息,并顯示在屏幕上。 【任務要求】 運用類的思想來實現員工信息管理系統的編寫。實現以下操作： 員工信息系統包括：工號、姓名、年齡、性別、所屬部門、職稱、入職時間、聯系電話。 實現功能有：輸入員工信息、輸出員工信息、統計員工信息、查詢員工信息、修改指定員工信息、刪除指定員工信息以及退出程序。

二、運營環境及開發工具

1、C語言以及C++語言

2、vc++6.0

3、Dev-C++

三、流程圖

1、系統流程圖

?

2、主函數流程圖

?3、具體函數流程圖略

? ? 很好畫的，可以參考上面的流程圖。

四、實現代碼
