相比之前的未完成版,这个去掉一些功能简化一下先做一个初版放上来了.

已完成的扩展方向:

A.换肤

B.user选择题目数量

C.阶乘

任务分配：

     我负责的是出题以及计算两个部分,界面换肤以及其他功能是同伴莫俊宇负责的,最后两个人一起进行整合以及调试

感想：

　　结队作业比起以往我一个人干要效率不少,这样我可以把我不擅长的部分交给队友,两个人各施其职,效率非常高,而且也能互相帮忙解决问题,程序的容错也比以往要好,两个人结队的时候注重的是交流,这样才能融合两个人不同的编码风格,让程序的质量进一步提升

　　这一次结队让我受益良多,也让我认识到编程队的重要性,期待与伙伴的下一次合作
