Hi i am sunil , i just started learning C# Programming .. while i was trying simple array program and printing the values.i dont clearly understand the meaning of this print statement .
/// Console.WriteLine("Element[{0}] = {1}", j, n[j]);

can'nt we just write this statement like this  for printing the array values
Console.WriteLine("Element are " , n[j]);

if not then plz.. explain........Thanks in advance.. complete program is written belowusing System;
namespace ArrayApplication
{
   class MyArray
   {
      static void Main(string[] args)
      {
         int []  n = new int[10]; /* n is an array of 10 integers */
         int i,j;


         /* initialize elements of array n */         
         for ( i = 0; i < 10; i++ )
         {
            n[ i ] = i + 100;
         }

         /* output each array element's value */
         for (j = 0; j < 10; j++ )
         {
            Console.WriteLine("Element[{0}] = {1}", j, n[j]);
         }
         Console.ReadKey();
      }
   }
}

In the line below you have 3 objects

1) The format : "Element[{0}] = {1}"

2) Parameter 0 : j   -  Replaces the {0} in the format

3) Parameter 1 : n[j] - Replaces the {1} in the format

Console.WriteLine("Element[{0}] = {1}", j, n[j]);

Have your ran your code that you suggest? "Elemet are", n[j]

That gives nothing but following output:

Elements are

Elements are

Elements are

.

.. 7 more times

Back to your original question:

heres hes storing the positional values, value of j goes to {0} or 0th argument and n[j] goes to {1} or 1st argument.

You may add even more things like , ("Element[{0}] = {1} ${2}",j,n[j],chand)

This will added chand in end of all prints.

Another thing that depicts here is that, Array starts from 0 not 1, value of 0th element is 100 (which is 0+100) and so on...
