职工信息管理系统：

1. 存在一个数据文件，用来存储职工各种信息：职工号，姓名，年龄，性别，
   邮编，部门，工资

2. 可以注册新职工；

3. 允许修改职工信息

4. 允许删除职工信息；

4，按照按照姓名和部门查询职工信息；

1. 可以按照工资多少进行排名，

2. 可以浏览所有职工信息；

.有一个主界面，供选择和调用上述选项。

.用C++中，文件和链表实现

1、头文件control.h

#ifndef CONTROL_H
#define CONTROL_H#include <iostream>
#include <vector>
#include <string>
#include <functional>
#include <algorithm>
#include <fstream>
using namespace std;class Stuff
{
public:string ID;string name;string age;string sex;string postcodes;string department;string salary;
};
class Control
{
public:void system_init(vector<Stuff> &p);void jiemian();void Creat_list_tail(vector<Stuff> &p);void Del(vector<Stuff> &p); void Change(vector<Stuff> &p);void Search(vector<Stuff> &p);void Display(vector<Stuff> &p);void Sort(vector<Stuff> &p);
};#endif

2、主函数Staff management system.cpp
