需求分析：

1.整数加减乘除的测试；

2.分数加减乘除的测试；

3.最大公约数测试；

4.判断真分数测试；

计算模块：

public int gcd(int a, int b)//公约数

        {

            if (a == 0)

            {

                return b;

            }

           else if (b == 0)

            {

                return a;

            }

            else

            {

                return gcd(b % a, a);

            }

        }

        public int Calculate(int type, int op1, int op2)//整数四则运算

        {

            int result = 0;

            if (type == 1)

            {

                result = op1 + op2;

            }

            if (type == 2)

            {

                result = op1 - op2;

            }

            if (type == 3)

            {

                result = op1 * op2;

            }

            if (type == 4)

            {

                result = op1 / op2;

            }

            return result;

        }

        public string CalculateFengsu(int up1, int down1, int up2, int down2, int type)//分数四则运算

        {

            string result = "";

            if (type == 1)

            {

                up1 = (up1 * down2 + up2 * down1);

                down1 = down1 * down2;

                up2 = gcd(up1, down1);

                up1 = up1 / up2;

                down1 = down1 / up2;

                result = up1.ToString() + "/" + down1.ToString();

                return result;

            }

            if (type == 2)

            {

                up1 = (up1 * down2 - up2 * down1);

                down1 = down1 * down2;

                up2 = gcd(up1, down1);

                up1 = up1 / up2;

                down1 = down1 / up2;

                result = up1.ToString() + "/" + down1.ToString();

                return result;

            }

            if (type == 3)

            {

                up1 = up1 * up2;

                down1 = down1 * down2;

                up2 = gcd(up1, down1);

                up1 = up1 / up2;

                down1 = down1 / up2;

                result = up1.ToString() + "/" + down1.ToString();

                return result;

            }

            if (type == 4)

            {

                up1 = up1 * down2;

                down1 = down1 * up2;

                up2 = gcd(up1, down1);

                up1 = up1 / up2;

                down1 = down1 / up2;

                result = up1.ToString() + "/" + down1.ToString();

                return result;

              

            }

            

            return result;

        }

        public string CalculateZfengsu(int up1,int down1)//判断及生成真分数

        {

            string result = "true";

            int mid = 0;

             

                if (up1 > down1)

                {

                    mid = down1;

                    down1 = up1;

                    up1 = mid;

                    result = up1.ToString() + "/" + down1.ToString();

                    return result;

                }

                    if (up1 == down1)

                    {

                        down1 += 3;

                        result = up1.ToString() + "/" + down1.ToString();

                        return result;

                    }

    return result;

}

一、公约数测试：

gcd(int a, int b)

二、整数加减乘除测试：

Calculate(int type, int op1, int op2) //其中type为运算类型，op1，op2为整数。

三、分数四则运算：

 CalculateFengsu(int up1, int down1, int up2, int down2, int type) //其中up1，up2为分子，down1，down2为分母，type为运算类型。

四、判断真分数：

CalculateZfengsu(int up1,int down1) //up1，down1分别为分子分母。

五、代码覆盖率：

 

 六、小结：

 这是结对编程的第二次作业，难度会大一些，万事开头难，不知道从何下手，摸索了一段时间后才开始做的，一些代码也不够熟练，总得好好的去找其他同学请教请教才行。还有就是要看以前的书籍。

七、Git 版本控制系统保存工作文件：
