why is {0} needed in this sample code?

[SurvivorTiger]

Hi everyone,
I'm new to C++ .NET so this question might be a little too easy..maybe...

for(i=0; i<2; i++)
{
for(int j=0; j<3; j++)
Console::Write(&quot;{0} &quot;, __box(arr[j]));

Console::WriteLine();
}

As you can see there are two for loops that are to print out different values of a 2D array names arr. What I don't understand is this part of the code &quot;{0} &quot;, ....if i eliminate that part, nothing happens and it displays the data just as it would with that section of the code.
Thanks in advance

It's one of the overloaded Write() methods of the Console class. The first parameter in this case is a format string. For more information see the article Formatting Overview in the .NET documentation

[C#]
public static void Write(
   string format,
   object arg0
);
