How to store the list of values to array from 2D array

anbutechie has asked for the wisdom of the Perl Monks concerning the following question:

Hi,
Lets take, b is a 2D array.

$b[0][0]=00;
$b[0][1]=01;
$b[0][2]=02;
$b[1][0]=10;
$b[1][1]=11;
$b[1][2]=12;
$b[2][0]=20;
$b[2][1]=21;
$b[2][2]=22;
@x=@b[0];
[download]

@x returns ARRAY(0x225130)
But expected is (0,1,2)

Regards,
Anbarasu

That sort of structure is called an array of arrays in Perl, which is short for an array of references to array. Each element of `@b` is a reference. If you want the contents of the referenced array, you'll need to dereference the element of `@b`: `@x = @{$b[0]};` [download]	[reply] [d/l] [select]

If you except 0,1,2 to be printed then the code should be likewise `$b[0][0]=00; $b[0][1]=01; $b[0][2]=02; $b[1][0]=10; $b[1][1]=11; $b[1][2]=12; $b[2][0]=20; $b[2][1]=21; $b[2][2]=22; my @x = $b[0];` [download]	[reply] [d/l]

No. `my @x = @{$b[0]};`	[reply] [d/l]
