C# -- 隨機數產生的字母金字塔

1. 代碼實現:

        static void Main(string[] args)
        {   
            showNpoint(25);
            Console.ReadKey();
        }

        private static void showNpoint(int count)
        {
            Random r = new Random();

            string[] strE = { "A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"};

            for (int i = 1; i <=count; i++)
            {
                for (int j = 1; j <=count-i; j++)
                {
                    Console.Write(" ");
                }

                for (int k = 1; k <= 2*i-1; k++)
                {
                    Console.Write(strE[r.Next(0,25)]);
                }
                Console.WriteLine();
            }
        }
