打印星星图案。打印的行数n由键盘输入，下面例图中 n=5

//星星public static void star1(){Console.WriteLine("请输入打印的行数：");int n = int.Parse(Console.ReadLine());for (int i = 1; i <= n; i++){if (i < n){for (int j = 1; j <= i - 1; j++){Console.Write(" ");}Console.Write("**");for (int k = 1; k <= 2 * (n - i - 1); k++){Console.Write(" ");}}else{for (int j = 1; j <= 2 * n - 3; j++){Console.Write(" ");}}Console.Write("**");Console.WriteLine();}Console.ReadLine();}static void Main(string[] args){//对此类方法的调用star1();}
