Blog第三次作业

第三次BLOG作业

前言: 不知不觉又度过了一个月，这个月主要的学习内容为PTA的电话计费和实验了。

　　这次迭代作业题量不多，难度也有所下降，老师的类图也给出来了，其实更多的是自己的理解。

　　PTA：电话计费:

　　直接把最终代码奉上叭：

　　以上就是这次作业的代码了。老师的类图：

　　说一下以上作业心得吧。这次作业是分三次做完的，老师给出了几个类图，在最开始的时候，还是有点不明白，这几个类的作用，也算是跌跌撞撞中摸索出来了方法。

　　其实就是搞清楚几个大类的层次关系。用户和用户记录，用户记录和用户规则，用户和用户规则。我的逻辑是用户记录管理这多条记录，然后用户通过收费模式能够计算出该模式的总价，然后不同模式下有着相应的收费标准，不同套餐得到用户的记录，然后把所有规则都循环对应计费，得出总价。

　　遇到的问题最初的数据输入，比如正则表达式的应用可能会比较复杂，涉及到时间的这部分，然后就是对数据切割，然后打包处理成记录（callRecord），然后一些区号的区分，手机的判定，格式的判定都有藏很多细节。

　　然后对类设计也有一些感悟，比如一些数据的管理类之间的关系，使用者和终端的关系。如何判断设计两个类之间的关系等等。比如User和ChargeMode的依赖关系，ChargeMode和Rule的组合关系等。理解好类间关系，之后的增加Mode和增加Rule也就是水到渠成的事，前面的代码都不需要改动（这里吐槽一下最后一次作业代码超限问题，不得不删除一些类，然后有一些组合关系例如UserRecords和CallRecord，删着删着就删不明白了）。
