C++：基于多态的企业职工系统程序设计
（一）作者瞎叨叨：
时隔五日，甚是想念。今天回来更新一下自己的学习成果啦！本次程序设计是【黑马程序员~C++】中的C++核心编程的程序设计题，基于多态的企业职工系统程序设计，由于我学习速度较快，还不够扎实，这个程序设计结果是介于理解与独立编程之间的，也就是说一定程度上参考了官方程序的思想再加上自己的思考完成的这一个程序设计，也算是我的一个阶段性成果啦！

（二）设计要求：
（三）程序相关事项（可见于.cpp程序文件开头）：
/*
开发项目：【黑马程序员~C++核心编程程序设计】基于多态的企业职工系统
程序结构：头文件：boss.h （boss子类声明） employee.h (employee子类声明)
manager.h （manager子类声明） worker.h （worker父类声明）
workerManager.h （workerManager类声明，用于调用函数）
源文件：boss.h （boss子类函数定义） employee.h (employee子类函数定义)
manager.h （manager子类函数定义） worker.h （worker父类函数定义）
workerManager.h （workerManager类函数定义，用于调用函数）
开发语言：C++开发环境：Windows Visual Studio 2022
程序实现：可以完成对职工的添加，显示，修改，删除，查找，排序，清空操作，并且可以写入文件保存再读取
程序特性：由于C++核心编程我学习的速度有点快，还不那么扎实，是借助了原版程序编写的，在编写的同时将将其完善，增加了空文件的全方位检测机制，增加了工号查重机制，完善程序引导，增加输入监测机制程序是基于多态完成的，构建了两个大类，其中一个类增加了三个子类，使得程序清晰明了
