项目结构
-
头文件(Header Files)
employee.h
: 定义了一个基本的职工类。manage.h
: 继承自Employee
类,用于管理员工。boss.h
: 同样继承自Employee
类,代表公司的高层管理人员。workermanager.h
: 主要管理类,负责整体的职工信息管理。
-
源文件(Source Files)
employee.cpp
: 实现了Employee
类的方法。manage.cpp
: 实现了Manage
类的方法。boss.cpp
: 实现了Boss
类的方法。workermanager.cpp
: 实现了WorkerManager
类的方法。
-
其他文件
main.cpp
: 项目入口点,通常用于创建WorkerManager
对象,并启动系统。
主要功能
- 显示菜单 (
ShowMenu
): 提供用户交互界面,展示可用的操作选项。 - 添加职工 (
Add_Emp
): 允许用户输入新的职工信息,并将其添加到系统中。 - 删除职工 (
Del_Emp
): 根据输入的职工编号删除相应的职工信息。 - 修改职工信息 (
Mode_Emp
): 更改现有职工的信息。 - 查找职工 (
Find_Emp
): 根据编号或姓名搜索特定的职工。 - 排序职工 (
Sort_Emp
): 按编号升序或降序排列职工列表。 - 退出系统 (
exitSystem
): 清理资源并退出程序。
