随机抽奖程序
string[] s = new string[] { "A", "B", "C", "D", "E", "F", "G" };
Random rand = new Random();
for (int i = 0; i < 50; i++)
{
int n = rand.Next(s.Length);//随机数赋值
Console.WriteLine(s[n]);
System.Threading.Thread.Sleep(50);//线程等待ms
Console.Clear();//清除屏幕,把计时的数也清除了
}
int m = rand.Next(s.Length);
Console.WriteLine("恭喜" + s[m] + "中奖");
冒泡排序程序
int[] m = new int[8];
Console.WriteLine("任意输入" + m.Length + "个正整数排序");
for (int i = 1; i <= m.Length; i++)
{
m[i - 1] = Convert.ToInt32(Console.ReadLine());//给数组输入数据
}
int mid;//定义中间变量
for (int i = 0; i < m.Length; i++)
{
for (int j = 0; j < m.Length - i - 1; j++)
{
if (m[j] < m[j + 1]) //将大的数放到前面
{
mid = m[j];
m[j] = m[j + 1];
m[j + 1] = mid;
}
}
}
for (int i = 0; i < m.Length; i++)
{
Console.Write(m[i] + ","); //输出排好序的数组
}
