篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了结对编程项目-四则运算相关的知识，希望对你有一定的参考价值。
根据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，我们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) 2 { 3 if (cal == 1) 4 { 5 int[] num1; 6 int[] num2; 7 int i, r1, r2; 8 int n = int.Parse(textSum.Text); 9 Random r = new Random(); 10 num1 = new int[100]; 11 num2 = new int[100]; 12 for (i = 0; i < n; i++) 13 { 14 15 r1 = r.Next(int.Parse(textF.Text), int.Parse(textT.Text)); 16 r2 = r.Next(int.Parse(textF.Text), int.Parse(textT.Text)); 17 int s = r1 + r2; 18 if ((r1 != 0 && r2 != 0)&&(r1>r2)) 19 { 20 num1[i] = r1; num2[i] = r2; 21 } 22 else 23 { 24 i--; 25 continue; 26 } 27 } 28 for (i = 0; i < n; i++) 29 { 30 31 if (num1[i] != 0 && num2[i] != 0) 32 { 33 34 listView1.Items.Add("(" + num1[i] + ")" + Getstr2(1) + "(" + num2[i] + ")" + "="); 35 } 36 37 } 38 39 } 40 if (cal == 2) 41 { 42 int[] num1; 43 int[] num2; 44 int[] num3; 45 int i, r1, r2, r3; 46 int n = int.Parse(textSum.Text); 47 Random r = new Random(); 48 num1 = new int[100]; 49 num2 = new int[100]; 50 num3 = new int[100]; 51 for (i = 0; i < n; i++) 52 { 53 54 r1 = r.Next(int.Parse(textF.Text), int.Parse(textT.Text)); 55 r2 = r.Next(int.Parse(textF.Text), int.Parse(textT.Text)); 56 r3 = r.Next(int.Parse(textF.Text), int.Parse(textT.Text)); 57 if ((r1 != 0 && r2 != 0 && r3 != 0)&&((r1-r2)>r3)&&(r1>r2)&&(r2>r3)) 58 { 59 num1[i] = r1; num2[i] = r2; num3[i] = r3; 60 } 61 else 62 { 63 i--; 64 continue; 65 } 66 } 67 for (i = 0; i < n; i++) 68 { 69 70 if (num1[i] != 0 && num2[i] != 0 && num3[i] != 0) 71 { 72 73 listView1.Items.Add("(" + num1[i] + ")" + Getstr2(1) + "(" + num2[i] + ")" + Getstr2(1) + "(" + num3[i] + ")" + "="); 74 } 75 76 } 77 } 78 if (cal == 3) 79 { 80 int[] num1; 81 int[] num2; 82 int[] num3; 83 int[] num4; 84 int i, r1, r2, r3, r4; 85 int n = int.Parse(textSum.Text); 86 Random r = new Random(); 87 num1 = new int[100]; 88 num2 = new int[100]; 89 num3 = new int[100]; 90 num4 = new int[100]; 91 for (i = 0; i < n; i++) 92 { 93 94 r1 = r.Next(int.Parse(textF.Text), int.Parse(textT.Text)); 95 r2 = r.Next(int.Parse(textF.Text), int.Parse(textT.Text)); 96 r3 = r.Next(int.Parse(textF.Text), int.Parse(textT.Text)); 97 r4 = r.Next(int.Parse(textF.Text), int.Parse(textT.Text)); 98 int s1 = r1 - r2; 99 int s2 = r3 - r4; 100 if ((r1 != 0 && r2 != 0 && r3 != 0 && r4 != 0)&&(r1>r2)&&(r3>r4)&&(s1>s2)) 101 { 102 num1[i] = r1; num2[i] = r2; num3[i] = r3; num4[i] = r4; 103 } 104 else 105 { 106 i--; 107 continue; 108 } 109 110 } 111 for (i = 0; i < n; i++) 112 { 113 if (num1[i] != 0 && num2[i] != 0 && num3[i] != 0 && num4[i] != 0) 114 listView1.Items.Add("(" + num1[i] + ")" + Getstr2(1) + "(" + num2[i] + ")" + Getstr2(1) + "(" + num3[i] + ")" + Getstr2(1) + "(" + num4[i] + ")" + "="); 115 116 } 117 } 118 if (cal == 4) 119 {

总结：经过了几天的努力，我们共同完成了这次作业，在这期间存在着不同的问题，总之还是觉得自己懂的太少了，应该增加些代码量，做程序的时候不能急，应该一步步的来，问问题也是很重要的一部分，随着计算机技术的成熟，我们应该增加自己对计算机的认识和努力提高我们的专业知识，这次我们通过查找其他人博客学习到了很多东西，总之觉得应该少一些花哨的东西，多务实一点，多打一些代码。
