    class Program

        static void Main(string[] args)
        {


            int[,] twoDimensionalArray = new int[4, 3];
            int sum=0;
           
            for (int i = 0; i < 4; i++)
            {
                for (int j = 0; j < 3; j++)
                {
                    Console.Write("Enter value [{0}][{1}]: ", i,j);
                    twoDimensionalArray[i, j] = int.Parse(Console.ReadLine());
                }
            
            }


            for (int i = 0; i < 4; i++)
            {
                for (int j = 0; j < 3; j++)
                {
                    sum += twoDimensionalArray[i, j];
                }
            }
            double average = (double)sum / 12.0;
            Console.WriteLine("The sum is: {0} ", sum);
            Console.WriteLine("The average is: {0} ", average);




            Console.ReadLine();
        }
