C++职工管理系统 C++利用多态实现职工管理系统(项目开发)

双鱼座boyy 人气:0

分析

首先看一下这个项目的文件:

主要分为两部分:

主体部分:
main.cpp和workManager.h,workManager.cpp职工部分(这里采用多态的方式编写):
主要是worker.h和worker.cpp
三种职位:boss,employee,manager

经过分析是否大概知道了其中各部分的意思呢?

看起来这里面有很多,但是正是这种多个文件编写才时代码更加简洁。

所以在正式写项目之前一定要先考虑好整体架构,在进行编写。

项目整体架构:

这个项目的难度并不大,主要是要学会这个项目整体架构是怎样安排的。

左边是主体部分。

主要是整个项目的功能,将主界面的所有功能通过代码和右边的不同人之间进行实现。

包含了上面几个功能函数,还有一些没有写出来

右边则是三种职工的信息。

每个人都有自己的姓名,编号,职位,然后包含两个函数,显示个人信息和获取岗位信息。

主要是通过数组进行存储的

其它的也没什么需要过多介绍的,主要是要理解上面的整体架构图,详细的代码编写并不算复杂

部分运行截图
