环境配置
下载git并下载四则运算到电脑上
vs在之前已经安装并且配置好了，当时安装的时候遇到一些困难，但是现在并没有什么困难了。
代码设计思路
代码如下：

else

{
if (e == "+")

else if (e == "*")

else
{
if (d != 0)
{

{

}
}

}
}

思路为：先判断符号，两个符号就是三位数，三个符号就是四位数。再去处理符号优先级，然后是计算过程。
github克隆及提交过程
下载
然后到本地
然后上传成功的：
单元测试和回归测试的过程
右键项目，新建，选择test，进行测试，这里我测试的是jisuan：
总结
1、github和git都是没有用过的东西，进了github的网站还觉得有点懵，全英语，感觉有点高级，但是多看几眼发现还是挺方便的一个东西。git用起也很舒服，下载直接用，指令比较简单，也不需要配置什么环境之类的。总的来说这两个东西以前没有用过还觉得有点可惜。
2、以前测试软件可以不可以用就直接运行排错，现在发现单元测试和回归测试确实是好用，我用的vs2013,之前没有下载组件，找了大半天的测试都没找到，然后去百度vs单元测试也发现不一样，这也算低级错误嘛，结果一搜vs2013单元测试一下就找到了。单元测试的思想感觉以前也想到过，但是没真正的试过，知道这种方法的话，以后估计还是经常用。
3、vs以前学c#的时候经常用，但是距今也有很长时间没用了，拿起来还是比较手生，要找些功能或者要写一些语句都忘记怎么操作了。看来这些工具还是要多用，代码也要多写。
