            int x, y;

            
            Console.Write("   ");
            Console.Write('\t');
            for (y = 0; y < 10; ++y)
            {
                Console.Write(string.Format("{0,3}",y));
                Console.Write('\t');
            }

                Console.Write('\t');
                for (y = 0; y < 10; ++y)
                {
                    Console.Write(string.Format("{0:0.000}", Math.Sqrt(x * 10 + y)));
