C# 数组及冒泡排序的简单应用——双色球

Random r = new Random();
int[] caipiao = new int[7];//建立彩票数组
Console.WriteLine("双色球随机：");
while (true)
{
for (int i = 0; i < 6; )//随机红球
{
if (i == 0)
{
caipiao[i] = r.Next(1, 34);
i++;
}
else
{
int temp = r.Next(1, 34);
for (int j = 0; j < i; )
{
if (temp == caipiao[j])
{
temp = r.Next(1, 34);
j = 0;//随机出的数再次从第一个数开始遍寻
}
else
{
j++;
}
}
caipiao[i] = temp;//将不重复的数 赋值给I的下一位
i++;
}
}
for (int i = 0; i < 6; i++)//冒泡排序
{
for (int j =0; j < 6-i-1; j++)
{
int t = 0;
if (caipiao[j] < caipiao[j+1])
{
t = caipiao[j];
caipiao[j] = caipiao[j+1];
caipiao[j+1] = t;
}
}
}
caipiao[6] = r.Next(1, 17);
Console.Write("红球：");

for (int i = 0; i < caipiao.Length; i++)
{
if (i == 6)
{
Console.Write("篮球：" + caipiao[i] + "\t");
}
else
{
Console.Write(caipiao[i] + "\t");
}
}
Console.ReadLine();
