1、精選優(yōu)質(zhì)文檔-傾情為你奉上#include<iostream>#include<fstream>#include<string>#include<iomanip>using namespace std;#define M 200 /可以存信息總量int N=0; /學(xué)生總量class studentpublic:student();void set(); /初始化信息，第一次對信息的錄入void add(); /添加學(xué)生信息void del(); /刪除某學(xué)生信息void change(); /修改某學(xué)生信息 void search(); /查詢

2、某學(xué)生信息void display(); /顯示全部學(xué)生信息private:static int num;string name,sex,age,birthday,address,tel,Email;int student:num=1000;student:student() /初始化文件void student:set()int i;string setname,setsex,setage,setbirthday,setaddress,settel,setEmail;ofstream outfile;outfile.open("f1.txt",ios:out); /-打開
