这是我和本班　　韦艺林学号130201122 博客地址：http://www.cnblogs.com/yilinwei编程

功能：咱们根据老师提出的做业要求金本上完成了一个带有用户界面的四册运算，能够根据我的要求选择题目数量和取值范围，并能够进行混合四则运算，在原有能够分数运算的基础上加上了正负数运算，使其更加完整。dom

我和她的此次做业并未进行详细的分工，咱们一块儿进行了页面的布局的代码的实现。布局

优缺点：咱们相互指导，有时会就没一段代码发生争吵，但咱们会细心听取对方的意见，综合咱们的想法去最好的方案。this

结对编程的优缺点：结对编程能够集中全部的的想法，促进编程的实现，正所谓众人拾材火焰高，可是在结对编程中也容易出现问题，发生纠纷，由于每一个人都是一个个体，都有本身的想法，有时候很难让对方接受本身的想法，咱们也出现过这样的问题，但通过讨论，你们都获得满意的方案。spa

如下为本次做业的代码：orm

form1blog

Form1：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Windows.Forms;


namespace WindowsFormsApplication2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void btn1_Click(object sender, EventArgs e)
        {

            Form2 form = new Form2();
            form.Show();


        }

    }
