馮老師給出的作業我們解決了最基本的功能以及基本設定參數：
1) 題目的數量（個人項目的要求）
2) 數值的範圍（個人項目的要求）
3) 題目中最多幾個運算符
4) 題目中是否有乘除法
5) 題目中有無負數
我們本次兩個小組合作完成本次作業，我和李成帥同學的小組主要負責以下功能：
1） public void Build_Mul_Div_NoMinus函數
2） public void Build_NoMul_NoDiv_Minus函數
1.主界面
public void Build_Mul_Div_NoMinus函數代碼如下： 1 public void Build_Mul_Div_NoMinus(int cal)
