🎃C++动态实现职工管理系统,较全面。
一、🧥总结
提示:简单思维导图,总结我的思路:
很简单,老套路,源文件写函数实现,头文件写函数声明,头文件名字要一样。
👓关于using namespace std的使用我不解释。
1.🧶代码分布
2.🧵功能分布成员分布
排序我用的选择排序,注意程序运行后,输入添加成员信息的时候注意信息成员类型,不要写int型形写成字符型,这个我基本没写判断机制。
二、👔源码
1.👕头文件
- workerManager.h
代码如下(示例):
#pragma once
#include<iostream>
#include"worker.h"
#include<fstream>
#define FILENAME "empFile.txt"
class workerManager
{
public:
//构造函数
workerManager();
//菜单功能
void showMenu();
//添加成员
void Add_Emp();
//退出
void exitSystem();
//保存文件
void save();
//析构函数
~workerManager();
//记录文件中的人数个数
int m_EmpNum;
//员工数组的指针
Worker **m_EmArray;
//判断空文件
bool m_FileIsEmpty;
//统计人数
int get_EmpNum();
//初始化数组
void init_Emp();
//显示职工
void show_Emp();
//删除职工
void del_Emp();
//判断职工是否存在
int IsExist(int id);
//修改功能实现
void Mod_Emp();
//查找职工函数声明
void Find_Emp();
//排序算法
void Sort_Emp();
//清空文件
void Clean_File();
};
2.worker.h
#pragma once
#include<iostream>
#include<string>
using namespace std;
//职工抽象类
class Worker
{
public:
//显示个人信息
virtual void showInfo() = 0;
//获取岗位名称
virtual string getDeptName() = 0;
public:
int m_Id;//职工编号
string m_Name;//职工姓名
int m_DeptId;//职工所在部门名称编号
};
3.Boss.h
#pragma once
#include<iostream>
#include<string>
#include"worker.h"
class Boss : public Worker
{
public:
//构造函数
Boss(int id, string name, int dId);
//显示个人信息
virtual void showInfo();
//获取职工岗位名称
virtual string getDeptName();
};
4.manager.h
#pragma once
#include<iostream>
#include<string>
#include"worker.h"
using namespace std;
class Manager : public Worker
{
public:
//构造函数
Manager(int id, string name, int dId);
//显示个人信息
virtual void showInfo();
//获取职工岗位名称
virtual string getDeptName();
};
5.employee.h
#pragma once
#include<iostream>
#include<string>
#include"worker.h"
using namespace std;
class Employee : public Worker
{
public:
//构造函数
Employee(int id, string name, int dId);
//显示个人信息
virtual void showInfo();
//获取职工岗位名称
virtual string getDeptName();
};
2.🦺源文件
- 职工管理系统.cpp
代码如下(示例):
#define _CRT_SECURE_NO_WARNINGS 1
#include "workerManager.h"
using namespace std;
int main()
{
while (true)
{
workerManager wm;
wm.showMenu();
cout << "请输入功能对应数字:";
int choice = { 0 };//用户输入的选择
cin >> choice;
switch (choice)
{
case 0:
/*退出*/
wm.exitSystem();
break;
case 1:
/*添加*/
wm.Add_Emp();
break;
case 2:
/*显示*/
wm.show_Emp();
break;
case 3:
{
/*删除*/
wm.del_Emp();
break;
}
case 4:
/*修改*/
wm.Mod_Emp();
break;
case 5:
/*查找*/
wm.Find_Emp();
break;
case 6:
/*排序*/
wm.Sort_Emp();
break;
case 7:
/*清空*/
wm.Clean_File();
break;
default:
system("cls");
break;
}
}
return 0;
}
