1、九九乘法表class Program static void Main(string args) for (int a = 1; a = 9; a+) for (int b = 1; b b) if (b c) Console.WriteLine(0,1,2, a, b, c); else if (c a) Console.WriteLine(0,1,2, c, a, b); else if (b a) if (a c) Console.WriteLine(0,1,2, b, a, c); else if (c b) Console.WriteLine(0,1,2, c, b, a); 值日问

2、题class Program static void Main(string args) int today; do Console.WriteLine(请输入今天星期几:); today = Convert.ToInt32(Console.ReadLine(); switch (today) case 1: Console.WriteLine(今天是张三值日); break; case 2: Console.WriteLine(今天是李四值日); break; case 3: Console.WriteLine(今天是王五值日); break; case 4: Console.WriteLi

3、ne(今天是赵六值日); break; case 5: Console.WriteLine(今天是王麻子值日); break; case 6: Console.WriteLine(今天是徐军值日); break; case 7: Console.WriteLine(今天是胡锦涛值日); break; case -1: break; default: Console.WriteLine(输入有误，请重新输入); break; while (today != -1); 猜0-100间的一个随机数class Program public static void Main() int a = new

4、Random().Next(100); /返回100内的非负随机数 int count=0;/猜的次数 int i=0;/猜的数字 Console.WriteLine(猜一猜这样一个随机数,它的范围是在零到一百之间.); for (count = 0; count 10; count+) i = Convert.ToInt32(Console.ReadLine(); if (i a)/如果输入的数大于产生的随机数 Console.WriteLine(您输入的数太大啦，重新输入一个小点的数); if (i = a)/如果输入的数等于产生的随机数 Console.WriteLine(不错，不错，您

5、猜对啦，恭喜！); break;/跳出循环 if (i = a & count = 10)/如果输入的数等于随机数，而且输入的次数等于十次 Console.WriteLine(恭喜您，您在最后一次猜对了); if (i != a & count = 10)/如果输入的数字不等于随机数，而且输入的次数已经到了十次 Console.WriteLine(对不起，您已猜了十次，而且都没有猜对，不能再猜了); Console.WriteLine(); Console.WriteLine(答案揭晓,产生的随机数为0:,a); 冒泡排序class Program public static void Mai

6、n() int d = 10, 15, 21, 43, 17, 98, 2, 74, 63, 10 ; int temp; /冒泡法排序 for (int i = 0; i d.Length-1; i+) for (int j = i + 1; j d.Length; j+) if (di dj) temp = di; di = dj; dj = temp; /输出排序结果 foreach (int i in d) Console.Write(0, , i); 6. 打印出 * * * * * * * * * *class Program public static void Main() f

7、or (int i = 1; i = i; a-) Console.Write( ); for (int b = 1; b 2 * i; b+) Console.Write(*); Console.WriteLine(); for (int j = 1; j = 5; j+) for (int c = 1; c 2*j; d-) Console.Write(*); Console.WriteLine(); 求随机数的和与平均值class Program public static void Main() int sum = 0; float average = 0.0f; Random r = new Random(); ArrayList myArrayList = new ArrayList(); Console.WriteLine(你想算几个数的和,并求它的平均值:); int iMax = int.Parse(Console.ReadLine(); for (int i = 0; i iMax; i+) myArrayList.Add(r.Next(0, 100); Console.WriteLine(这0个数是:, iMax); foreach (
