1.环境配置过程
我是用的网盘下的，因为当初装过很多次，所以这次比较容易，没什么问题，就说说以前的问题吧，就是安装路径不知道怎么改，因为这个软件内存大，因此，前面几次几乎都是装的c盘，这次也是改了路径，但依然有插件装在c盘，内存有剩了不多了，去网上百度说这是必须的，要不然有的软件没法运行就没管了。
2.代码设计
代码构思：我是想先用一个函数生成随机数，判断几位数进行计算，然后再传值给另外两个函数分别获得符号和数字，然后再用一个函数专门判断是否为小数，获得的数用list进行存储，然而后面发现行不通，不能计算，于是将两个函数去掉，换成两个分别计算2位和3位的函数，我一直觉得原来那种构思应该比较方便，然而后面算不出来，因此换成了这种，另外还有时间的关系，代码截图见下（好像截图不能太大，直接上传）：

3.github克隆项目以及提交代码
克隆项目简单，直接按照网上来的就行，下面的截图是我参照群里的文件模仿的一部分截图
4.单元测试和回归测试
这部分不会。
5.感想
尝试一个新东西太困难了，发现之前的c#代码也有很多不会，还要去查资料，另外这个git和测试之类的不会，这次是我自己时间拖太久了，现在发现赶不上，但我觉得我的代码还行，能勉强过去，其他的步骤软件是不怎么经操作过，希望最后能不能有这次试验的步骤之类的，网上和群里的git步骤真的对不上，群里那个master根本没看到，网页上的更别说了，单元测试网上点开测试后，只有一个属性，而我这有4个，都点进去哪一个和后面的步骤都合不上，更别说写测试之类的，因此深切渴求这次的步骤。
