这是一个基础的信息管理系统，有最基本的输入，删除，更改，查询功能。

这是功能1 增加职工信息
这是修改信息
这是按科室查询信息
其余基本功能不再赘述
我在该程序基础上新增了文件写入读取功能，不再关闭程序后数据清零。
以下是代码
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
template<typename type>
void diywrite(ofstream &stream,type &x)//写入文件
{
stream.write((char*)&x,sizeof(type));
}
void diywrite(ofstream& stream, string& str) //写入文件
{
int len = str.length();
stream.write((char*)&len, sizeof(int));
stream.write(str.c_str(), len);
}
ofstream fout("Empolyee.dat",ios::binary);
class Empolyee{
public:
static int p; //
int id;
string name;
string sex;
long long phonenumber;
string section;
int salary;
void AddEmpolyee();
void DeleteEmpolyee();
void UpdateEmpolyee();
void ReseachByName();
void ReseachByOffice();
void add();
void SaveInfo();
void Display();
friend void diysave(ofstream& stream, Empolyee &m);
} o[10];

以下是功能演示：
在退出程序后，程序根目录生成文件
，这就是储存数据的文件。用记事本打开显示
。
