            Console.WriteLine("Enter a any number between 1 to 10");
            int num1 = Convert.ToInt16(Console.ReadLine());
            if (num1 > 100){
                Console.WriteLine("Wrong number, {0}", num1);
            }else{
                if (num1 == 9){
                    Console.WriteLine("Jackpot number, {0}", num1);
                }else{
                    Console.WriteLine("Your number, {0}", num1);
                }

    }
  }
else
  {
    if (columnname != a && columnname != b && columnname != c
