  • 结对编程项目-四则运算

    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，我和李成帅同学的小组主要负责以下功能：

       1） public void Build_Mul_Div_NoMinus函数

       2） public void Build_NoMul_NoDiv_Minus函数

    1.主界面

    2.总体设计

    3.主要函数代码

    public void Build_Mul_Div_NoMinus函数代码如下：
      1  public void Build_Mul_Div_NoMinus(int cal)

    总结：经过了这些天的努力，我们成功完成了public void Build_Mul_Div_NoMinus函数和public void Build_NoMul_NoDiv_Minus函数的编写。编写代码的过程中，我们都学到了很多，认识到了代码编写的重要性，我们应该平时多打一些代码，熟悉整个程序的设计，这样切身参与到程序设计当中确实有非常重要的意义。这次的代码编写过程当中，我们也遇到了许多的问题，并且也通过我们的努力解决了这些问题。下次我们会继续努力！
