06.05 自我总结

一.面向对象编程

​面向过程编程，核心是编程二字，过程指的是解决问题的步骤，即先干什么、后干什么、再干什么、然后干什么……

与工厂的工艺流程差不多,前后都有影响

优点：复杂的问题流程化，进而简单化,调理清晰.

缺点:拓展性不行

二.对于我之前写的一个购物程序

'''0是注册功能,1是会员卡系统,2是购物功能,3是会员查找积分功能,4为会员积分兑换功能'''

三.鱼骨图分析异常

我用我之前工作,qc\qa工程师的经验给你们用鱼骨图分析法分析下我程序编写可能会碰到的异常情况

制图来之与X-Mind制作

先给大家简单介绍下鱼骨图分析方法.

首先是鱼骨,是我们要实现的一个某个功能,在工厂里呢这个叫工艺

第二步,大鱼刺我们就要画他的子功能,在工厂里是一个个工艺流程

第三步,小鱼刺是我们在实施子程序碰到的问题,在工厂是工艺流程中的一个个异常

然后我们要把一个个小鱼刺给解决掉,每次发现小功能异常就加小鱼刺,每次解决掉一个就拔去一个个小鱼刺,直到最后没有鱼刺为止.然后功能就慢慢完善了这是我在写我的小程序中碰到的问题

鱼骨图法是来分析异常解决异常的一种分析方法
