  • Best way to make sure I get all available options array/loop

    - by jaz872
    OK, here is my problem. I'm looking for the best way to loop through a bunch of options to make sure that I hit all available options. Some detail. I've created a feature that allows a client to build images that are basically other images layered on top of each other. These other images are split up into different groups. They have links on the side of the image that they can click to scroll through all the different images to view them. I'm now making an automated process that is going to run the function that changes the image when a user clicks one of the links. I need to make sure that every possible combo of the different images is hit during this process. So I have an array with the number of options for each group. The current array is [3, 9, 3, 3] My question is what is the best way to loop through this to make sure that all possible options will be shown? I apologize if this seems simple for someone out there, but I'm just having trouble wrapping my head around it. Hopefully if that person is out there, they can give a helping hand :)

Does anyone have any ideas? Thanks

  • Number of the different elements in an array.

    - by AB
    Is it possible to compute the number of the different elements in an array in linear time and constant space? Let us say it's an array of long integers, and you can not allocate an array of length sizeof(long). P.S. Not homework, just curious. I've got a book that sort of implies that it is possible.

  • post__not_in only excluding first post in array

    - by fightstarr20
    I am using two query_posts loops to firstly display a set of posts with a custom field of '2012' and then the second loop to display everything else excluding the posts it returned in the first... <?php if( get_query_var('paged') < 2 ) { ?> <?php query_posts( array( 'post_type' => 'project', 'meta_key' => 'start_date_year', 'meta_value' => '2012' )); $ids = array(); ?> <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?> <p>This is from Loop 1 - <?php the_title(); ?> - <?php the_id(); ?></p> <?php $ids[] = get_the_ID(); ?> <?php endwhile; endif; wp_reset_query(); ?> <?php } ?> <?php $paged = get_query_var( 'paged' ) ? get_query_var( 'paged' ) : 1; query_posts( array( 'post_type' => 'project', 'post__not_in' => $ids, 'orderby' => title, 'order' => ASC, 'paged' => $paged )); ?> <?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?> <p>This is from Loop 2 - <?php the_title(); ?> - <?php the_id(); ?></p> <?php endwhile; endif; wp_reset_query(); ?> <?php pagination(); ?> For some reason the 'post__not_in' = $ids is only excluding the first post ID in the array, I have print_r the array and it does contain all of the post IDs I want to exlcude. Anyone any ideas why only one ID is being excluded?

  • C#: reading in a text file more 'intelligently'

    - by DarthSheldon
    I have a text file which contains a list of alphabetically organized variables with their variable numbers next to them formatted something like follows: aabcdef 208 abcdefghijk 1191 bcdefga 7 cdefgab 12 defgab 100 efgabcd 999 fgabc 86 gabcdef 9 h 11 ijk 80 ... ... I would like to read each text as a string and keep it's designated id# something like read "aabcdef" and store it into an array at spot 208. The 2 issues I'm running into are: I've never read from file in C#, is there a way to read, say from start of line to whitespace as a string? and then the next string as an int until the end of line? given the nature and size of these files I do not know the highest ID value of each file (not all numbers are used so some files could house a number like 3000, but only actually list 200 variables) So how could I make a flexible way to store these variables when I don't know how big the array/list/stack/etc.. would need to be.

  • Changing Value of Array Pointer When Passed to a Function

    - by ZAX
    I have a function which receives both the array, and a specific instance of the array. I try to change the specific instance of the array by accessing one of its members "color", but it does not actually change it, as can be seen by debugging (checking the value of color after function runs in the main program). I am hoping someone can help me to access this member and change it. Essentially I need the instance of the array I'm specifying to be passed by reference if nothing else, but I'm hoping there is an easier way to accomplish what I'm trying to do. Here's the structures: typedef struct adjEdge{ int vertex; struct adjEdge *next; } adjEdge; typedef struct vertex{ int sink; int source; int color; //0 will be white, 1 will be grey, 5 will be black int number; adjEdge *nextVertex; } vertex; And here is the function: void walk(vertex *vertexArray, vertex v, int source, maxPairing *head) { int i; adjEdge *traverse; int moveVertex; int sink; traverse = vertexArray[v.number-1].nextVertex; if(v.color != 5 && v.sink == 5) { sink = v.number; v.color = 5; addMaxPair(head, source, sink); } else { walk(vertexArray, vertexArray[traverse->vertex-1], source, head); } } In particular, v.color needs to be changed to a 5, that way later after recursion the if condition blocks it.

  • Convert complex numerical array to associative array [PHP]

    - by user1500412
    I have an array data that look like this : Array ( [0] => Array ( [0] => Name: [1] => John W. [2] => Registration ID: [3] => 36 ) [1] => Array ( [0] =>Age: [1] => 35 [2] => Height: [3] => 5'11" ) [3] => Array ( [0] => Sex: [1] => M [2] => Weight: [3] => 200lbs ) [4] => Array ( [0] => Address ) [5] => Array ( [0] => 6824 crestwood dr delphi, IN 46923 )) And I want to convert it to associative array like this : Array( ['Name']=> John W. ['Registration ID']=> 36 ['Age']=> 35 ['Height'] => 5'11'' ['Sex']=>M ['Weight']=>200lbs ['Address']=>6824 crestwood dr delphi, IN 46923 ) I have no idea at all how to do this, since the supposed to be array column header were also in sequence, so it makes difficult to convert this array. Any help I appreciate, thx.

  • Find largest rectangle containing only zeros in an N&times;N binary matrix

    - by Rajendra
    Given an NxN binary matrix (containing only 0's or 1's), how can we go about finding largest rectangle containing all 0's? Example: I 0 0 0 0 1 0 0 0 1 0 0 1 II->0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 1 <--IV 0 0 1 0 0 0 IV is a 6×6 binary matrix; the return value in this case will be Cell 1: (2, 1) and Cell 2: (4, 4). The resulting sub-matrix can be square or rectangular. The return value can also be the size of the largest sub-matrix of all 0's, in this example 3 × 4.

  • Protecting from crashes (beyond bounds) with [object objectAtIndex:]

    - by Tom
    Hi! I'd like to know if there's a way to verify if an index exists before getting it. So it'd be way to protect my code against: *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (2) beyond bounds (0)' Like in PHP you can do: isset($object[10]); and it'll return true if it exists. Is there such a method in Objective-C/Cocoa? Thanks!

  • Selecting value from array results

    - by Swodahs
    Being new to learning PHP I am having trouble with understanding how to select/echo/extract a value from array result a API script returns. Using the standard: echo "<pre>"; print_r($ups_rates->rates); echo "</pre>"; The results returned look like this: Array ( [0] => Array ( [code] => 03 [cost] => 19.58 [desc] => UPS Ground ) [1] => Array ( [code] => 12 [cost] => 41.69 [desc] => UPS 3 Day Select ) [2] => Array ( [code] => 02 [cost] => 59.90 [desc] => UPS 2nd Day Air ) ) If I am only needing to work with the values of the first array result: Code 3, 19.58, UPS Ground --- what is the correct way to echo one or more of those values? I thought: $test = $ups_rates[0][cost]; echo $test; This is obviously wrong and my lack of understanding the array results isn't improving, can someone please show me how I would echo an individual value of the returned array and/or assign it to a variable to echo the normal way?

  • storing user input into string array in C

    - by Jcmoney1010
    I'm writing a program that is supposed to take in a list of names from the user, store them in an array, and then search through the list to check and see if the next name the user enters is part of the original list of names. The issue I'm having is that when I go to enter a list of names, it only saves the last name entered into the list. I've searched the web and this site for similar issues, but I can't seem to find anything that answers this issue specifically. Here is the part of code where I have problem void initialize(char names[][],const int MAX_NAMES,const int MAX_NAMELENGTH) { int i,Number_entrys; printf("How many names would you like to enter to the list?"); scanf("%d",&Number_entrys); if(Number_entrys>MAX_NAMES){ printf("Please choose a smaller entry"); }else{ for (i=0; i<Number_entrys;i++){ scanf("%s",names); } } printf("%s",names); } trying very hard to teach myself, so be gentle lol.

  • Assigning parameter as array length

    - by Jcolnz
    I am currently stuck with a homework assignment, question below; Define a default constructor for Deck that initialises the deck field with an array of size 0. Also define a constructor that takes an integer parameter and initialises the deck field with an array of that size. The constructor should also initialise every element with a new random MovieCard. The cards should be uniquely named. so far my code is public class Deck { MovieCard[] deck = new MovieCard[] {}; public Deck() { MovieCard deck[]; } public Deck(int size) { MovieCard deck = new MovieCard[]; } } Obviously this is incomplete by I can't find any references in my previous notes about referring a parameter into an array and setting this as the length.

  • PHP Undefined index - Occuring when the variable has a value in it

    - by Adam
    I have the following code that is being used to successfully upload images: $fileName = $_FILES['file']['name']; $fileSize = $_FILES['file']['size']; $fileType = $_FILES['file']['type']; $fileTmp = $_FILES['file']['tmp_name']; list($origWidth, $origHeight) = getimagesize($fileTmp); The catch is I'm getting an 'Undefined index' on each line. I have print_r($_FILES) just before this code and each array variable exists and I've echo out varibles like $fileName and can see each has a value. Also I have put this before this code block and it makes no difference: $fileName = $fileSize = $fileType = $fileTmp = ''; Any suggestions how I can ensure these variables are defined? thankyou
