一：设计思路（主要为本次作业设计思路）
1.主函数满足用户需求（整数还是分数运算还是混合运算/是否有乘除/多少个）
2.混合运算（两个数组，一个数组放随机生成的数，另一数组放随机生成的符号，利用栈来运算结果（栈一直有BUG，还没有实现））
二：源程序代码

三：截图
四：相关日志记录
五：结对工作照
六：总结
1.一下子就考虑的太多，思绪特别乱，总想着一步到位！
2.自己总给自己借口（还有WEB,数据库……也有作业），不能每天都花时间
3.程序中备注的地方都有小错或者未实现的地方
4.感觉自己代码很长，但是又无从下手去优化
1.主函数满足用户需求（整数还是分数运算还是混合运算/是否有乘除/多少个）
2.混合运算（两个数组，一个数组放随机生成的数，另一数组放随机生成的符号，利用栈来运算结果（栈一直有BUG，还没有实现））

三：截图
四：相关日志记录
五：结对工作照
六：总结
1.一下子就考虑的太多，思绪特别乱，总想着一步到位！
2.自己总给自己借口（还有WEB,数据库……也有作业），不能每天都花时间
3.程序中备注的地方都有小错或者未实现的地方
4.感觉自己代码很长，但是又无从下手去优化
