二、

需求分析：针对现有代码的改进分析，新开发功能的分析。
现有代码改进分析
目前就发现了两个bug，一个是功能键“复习”，他会回到主页面再次进行做题，功能键与实际内容不符，所以修改了功能键名称为“继续”。
另一个是他的正确率的计算有误，第一次运行程序的时候，计算出来的正确率结果是正确的，当点击了“继续”并再次做题之后，他的正确题数rn会累加，导致正确率计算出错，因此，我们在显示正确率之后令“rn=0.0”，避免他的累加。
图片展示：
原功能：
程序设计：针对新开发功能做设计，建议使用思维导图。
原本打算用二叉树来做随机算术题的产生。但后来观察了源代码，如果要使用二叉树的话要把他们的源代码全部推翻重来，如此一来，将耗费大量的时间与精力，于是后来还是放弃了，选择了一个较为简单，而且契合恶源代码的方法。

 代码如下：
