作业四: 结对编程项目---四则运算
1) 注明结对小伙伴的学号，姓名以及博客地址:
130201236 刘彦麟 博客地址：http://www.cnblogs.com/lylljj/
2) 实现的主要功能有哪些？
1、可以选择运算的形式，比如 +、-、 *、 /、 +-、 */、还有四种混合形式。
2、也可以选择难度，一个有三个选项，10以内、20以内以及100以内。
3、自动生成新的题目。
4、提交后可以判断对错。
3) 合作过程中主要负责完成了哪些工作？
刘彦麟同学主要负责了主要代码的编写，我参与一些简单代码的查阅以及复审。在写代码的过程中，遇到好多不会的问题。我们一起查询了百度和经过同学的帮助，我们最终写出了这样一个程序。
4) 结对的每一个人的优点和缺点在哪里 (要列出至少三个优点和一个缺点)。
刘彦麟同学的优点：认真仔细负责任，对于老师留的作业有很高的积极性，遇到不会的会努力想办法弄明白。
缺点是：基础薄弱
蔡强同学的优点：听话，对于分给我的任务能很好完成，积极配合组内工作，好学。
缺点：基础太薄弱
5) 总结在合作过程中结对编程的优点和缺点。
对于我这样基础不太好的同学来说，结对编程可以让我学到很多我根本就不知道的东西，让我这样不会的很多的同学也可以加入到编程里来，从零到有，而且，两个人1+1的力量是大于2的，所以合作很有用，希望以后多一些这样的作业。
缺点就是，没有一个共同编程的地方，因为我们不能出现在一个宿舍，所以沟通起来比较困难。
6) 至少附一张照片, 展现两人在一起合作编程的情况。
这些就是我们的代码：

下面的调试的截图
这是开始页面。
这是可以选择运算形式。
这是选择数的范围。
这是生成出题目的样子。
这是判断正误的结果。
