namespace Arrays2
{
    class Program
    {
        static void Main(string[] args)
        {
            //Multi Dimension 

            Console.WriteLine("Type 1 : Declaration");
            int[,] arr1 = {
                            {1,2,3,4 },
                            {11,22,33,44}
                          };
            for(int i=0;i<2;i++)

                }
                Console.WriteLine();
            }


            Console.WriteLine("\n\nType 2 : Declaration");
            int[,] arr2 = new int[2, 5];
            Console.WriteLine("Enter {0} values:", 2 * 5);
            for (int i = 0; i < 2; i++)

                }
                Console.WriteLine();
            }

            Console.WriteLine("\n\nType 3 : Declaration");
            Console.Write("Enter Rows :");
            int rows = Convert.ToInt32(Console.ReadLine());
            Console.Write("Enter Cols :");
            int cols = Convert.ToInt32(Console.ReadLine());
            int[,] arr3 = new int[rows,cols];

            for (int i = 0; i < rows; i++)

                for (int j = 0; j < cols; j++)
                {
                    arr3[i, j] = Convert.ToInt32(Console.ReadLine());
                }
            }
            for (int i = 0; i < rows; i++)
            {
                for (int j = 0; j < cols; j++)

            Console.ReadKey();
        }
    }
}
