用C# for函数做 1 1 2 3 5 8 13 前两个数相加等于第三个数

static void Main(string[] args)
{
int[] aa;
int tmp = 0;
int i = 0;
int n = 0;
aa = new int[2];
aa[0] = 1;
aa[1] = 1;
n = Convert.ToInt32(Console.ReadLine());
for (i = 0; i < n; i++)
{
if (2 > i)
{
Console.Write("{0} ",aa[i]);
}
else
{
tmp = aa[0] + aa[1];
aa[0] = aa[1];
aa[1] = tmp;
Console.Write("{0} ",tmp);
}
}
Console.WriteLine();
}
