I have two JavaScript arrays (A and B) that contain objects that I created. I want to check that all the objects in array A are contained in array B, but not necessarily in the same order. What is the best way to do this? Edit: They are all actual objects, not primitives, so I will need to compare their contents and structure as well ...

I am trying to teach myself C from a python background. My current mini-problem is trying to do less hard-coding of things like array lengths and allocate memory dynamically based on input. I've written the following program. I was hoping for suggestions from the community for modifying it in the following ways: 1.) Make first and ...
Say you are writing a 3d renderer with support for multi-texturing, where the number of texture units is configured through a compile time constant. Opposed to hard coding a single texture unit, your'e code now has to access texture-related parameters through arrays, and handle them through loops. Assuming a modern C++ compiler, are the...
Hey guys, I've got a float array camObjCoord declared as.. public static float camObjCoord[] = new float[8000]; I'm then filling its indexes in a class that does something like the following.. public void addcube(float highx, float lowx, float highz, float lowz){ //Constructing new cube... System.out.pri...
How to write this in another (perhaps shorter) way? Is there a better way to initialize an allocated array in C++? int main(void) { int* a; a = new int[10]; for (int i=0; i < 10; ++i) a[i] = 0; } ...
OK let's say I have this array: public int[][] loadBoard(int map) { if (map == 1) { return new int[][] { {2,2,24,24,24,24,24,1,3,0,0,0,1 }, { 2,2,24,23,23,23,24,1,3,0,0,0,1 }, { 1,1,24,23,23,23,24,1,3,3,3,3,1 }, { 1,1,24,24,23,24,24,1,1,1,1,3,1 }, { 1,1,1,1,7,1,1,1,1,1,1,3,1 }, { 6,1,1,1,7,7,7,7,7,1,1,1,1 }, { 6,3,3,1,3,3,3...
Its broken into lines because each arrayWithObjects: adds a new question (its a quiz game). But how come when its NSLogged it only displays the last arrayWithObjects: line.

If I dim an array to say, 5 elements, should it not fail if I go to add a 6th? I thought this used to require a redim. In .NET 2.0, I have a character array of length = 3. When I populate it from the db, one record had 4 characters in it and it successfully added all 4 characters to the array? ...
Following my last post about better syntax for arrays, I've decided to use JSON format for arrays and use a method to convert them into PHP code. Note that the ultimate goal of this is to be write a $config array in JSON and translate that into PHP code (so I can avoid having to use PHP's ugly array syntax): The function works fine fo...
Is there a single line in perl which does some magic like this. Array = [100,200,300,400,500]; percent = 50% new_Array = [50,100,150,200,250]; That is, I give an array and specify a percent. And it should give me a new array with the given percent of original array values. should take care of odd numbers and give me either ceiling ...
I just want to get my PHP array to a JS array, what am I doing wrong here? PHP: // get all the usernames $login_arr = array(); $sql = "SELECT agent_login FROM agents"; $result = mysql_query($sql); while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) { array_push($login_arr, $row["agent_login"]); } $js_login_arr = json_encode($log...
I am trying to fix a array problem where it stores images into arrays so I don't have to do it individualy. Here my code: tiles = new Image[NUM_TILES]; for (int i = 0; i < NUM_TILES; i++) { tiles[i] = getImage(getClass().getResource(String.format("tiles/t%d.png", i))); } weapon = new Image[2]; for (int xi = 0; xi < 2; xi++) { ...
Hello, I would like to use the GetVolumeInformation call to retrieve the name of a removable device. I can retrieve the name just fine and store into a TCHAR array variable szVolNameBuff. Here is my code for that: // Get Volume Information to check for NTFS or FAT TCHAR szFileSys[256]; TCHAR szVolNameBuff[256]; DWORD dwSerial ...
Possible Duplicate: Growable data structure in MATLAB So in my current MATLAB script, I have a very large indeterminate-sized growing array.

I need a method to traverse a multidimensional array in PHP without using function calls itself. Basically I have an array like this: $data = array( 'hoge' => 123, 'foo' => 456, 'bar' => 789, 'aaa' => array( 'abc' => 111, 'bcd' => 222, 'cde' => 333 ), 'bbb' => array( 'def' => arra...
Hi, How do I initialize an array to 0. I have tried this. my @arr = (); but it always throws me a warning "Use of uninitialized value" I do not know the size of the array before.

I need to walk over an array, and conditionally delete elements, in Perl. I know about slice, but am not sure how to use it in a foreach context. In Ruby, there is reject!: foo = [2, 3, 6, 7] foo.reject! { |x| x > 3 } p foo # outputs "[2, 3]" Is there a Perl equivalent? ...
