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：
