Var x = new Array(7);
obj notation with zeros
var x = []; for (var i = 0; i < 10; i++) x[i] = 0;
As a side note, if you modify....
Var x = [0,0,0,0,0,0];
filled with 'undefined'...
Using object notation
var x = [];

TIMTOWTDI fashion, you should either modify the function to return a new array:
sub trimArray { my @arr and then modify the array in place
sub trimInPlace { my $arrRef = shift; my @arr = @$arrRef; for my $val while (my @re = $sth->fetchrow....

Suppose you're calling a Win32 function that will fill in your byte array. You create an array of size 32, empty. Then pass it in to the Win32 function to be filled int, and use it later in your managed code. Does there exist the chance that the byte ...

So in situations like having a native function fill a byte[] no manually pinning of the array ....
An object will be unpinned.
Is, then the array would be pinned while being marshalled by the runtime, so no pinning would be needed.

Hi
In PHP, will these always return the same values?
//example 1 $array = array(); if ($array) { echo 'the array has items'; } // example 2 $array = array(); if (count($array)) { echo 'the array has items'; }
Thank you!

My class has an NSArray that is filled with objects. In my dealloc method, can I simply call release on my NSArray, or do I need to iterate the array and release all objects first?

NSArray retains objects....
You should be able to just release the NSArray that object explicitly - just releasing the NSArray may not dealloc the object outside of the array context.
Of sending release to all the objects stored in the array.

for (int i = 0...

If you use a jagged array, it works just fine:
// create array of arrays object[][] tableOfObject = new object[10][]; // create ....
You have to copy each item.
No, if you are using a two dimensional array it's not possible.

[] result.
Compare entries from both, adding them to a new array if you get a match.
Inside that loop, have another over the second array.
Loop over the first array.
Brute force.
Return list3.

I use a lot of lists and arrays but I have yet to come across a scenario in which the array list couldn't be used just as easily as, if not easier than, the linked list. I was hoping someone could give me some examples of when the linked list is notably...

In addition....
The base is the starting offset of the array.
Dimensional array using a row-major layout:
Address = Base + ((depthindex*col_size+colindex) * row_size + rowindex) * Element_Size
For a 3D array: type A[depth] [col] [row].
