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
