结对程序编程-四则运算
根据冯老师给出的作业我们解决了最基本的功能以及基本设定参数：
1) 题目的数量（个人项目的要求）
2) 数值的范围（个人项目的要求）
3) 题目中最多几个运算符
4) 题目中是否有乘除法
5) 题目中有无负数
我们本次两个小组合作完成本次作业，我们小组主要负责以下功能：
1） public void Build_NoMul_NoDiv_NoMinus函数
2） public void Build_Mul_Div_Minus函数
3）private string Getstr2函数
1.主要页面
2.大体的设计
3.函数代码

4.个人感想
这次作业对于我来说很难应为我的底子太差了许多代码看不懂，如果没有李红亮同学帮我可能我根本完不成这次作业。
我打算加紧学习C语言，不能连代码都看不懂。
