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:

130201201 蔡强 博客地址:http://www.cnblogs.com/cq130201201/

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?

我主要负责了主要代码的编写,蔡强同学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。

对于我们这样基础不太好的同学来说,结对编程可以让我们学到很多我根本就不知道的东西,让我们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。
