//設計一個學生評教系統，系統主要處理學生評教的相關信息。//其中，學生信息主要包括：學號、姓名、性別、聯系電話等內容，//教師信息主要包括:教師編號、教師名稱、任教課程編號、任教課程名、評教成績等內容，//請按照以下的功能要求設計系統。//【功能要求】//（1）定義學生類、教師類、評教類；//（2）輸入：學生、教師、評教信息的錄入；//（3）輸出：學生、教師、評教信息的輸出；//（4）編輯功能：可進對學生、教師、評教信息執行查詢、修改、添加、刪除等操作；//（5）菜單功能：每種功能的操作都是在菜單中進行相應選擇；//（6）最好用文件保存信息數據。#include<iostream>#include<fstream>#include<string.h>#include<conio.h> ?
