Hi, I've got a weird issue with Ruby. I want to read data from a file and put the data then into an array. The weird thing is, it's working in another script which does basically, the same thing. quoteArray = [] quoteFile = File.new("quotes.txt", "r") or die "Unable to open file..." quoteFile.each_line { |line| quoteArray.push line } ...
Hi everyone. Working with an array of dates (opening times for a business). I want to condense them to their briefest possible form.

I am trying to display results from a database where the results are contained in three tables. How do I echo out the results? $p-> works, but $img-> or $branch-> doesn't. What am I doing wrong? Example code is below Sample controller: $p_id = $this->uri->segment(3); $this->load->model('One_model'); $data['prop'] = $this-...
Hi, I'm trying to initialise a structure which ends with an array[0] (here, char iedata[0]) for the actual packet payload. If I try to initialise it inline, like this: struct some_packet pkt = { .elem1 = blah, .elem2 = bleh, .iedata = { 1, 2, 3, 4 } }; I get a warning from gcc: warning: (near initialization for ‘pkt.ie...
Hi everybody, I have tried to get my head around building a recursive function to handle formatting of a unknown depth multi-dimensional array to HTML and nested Divs. I thought that it should be a piece of cake, but no. Here's what I have come up with this far: function formatHtml($array) { $var = '<div>'; foreach ($array a...
Basically I have x amount of matrices I need to establish of y by y size. I was hoping to name the matrices: matrixnumber1 matrixnumber2..matrixnumbern I cannot use an array as its matrices I have to form. Is it possible to use a string to name a string (or a matrix in this case)? Thank you in advance for any help on this! for (int ...
So I have a couple of arrays $array_1 = Array('one','two','three'); $array_2 = Array('red','blue','green'); Is there a dynamic way to create the Setters and Getters for an array with single value entries? So the class would be something like: class xFromArray() { } So the above if I passed $array_1 it would generate something li...
Hi everybody, I have tried to make a function that iterates through the following array to flatten it and add parent id to children, where applicable. I just can't make it work, so I hope that anyone here has an idea of what to do: Here's the starting point: Array ( [0] => Array ( [id] => 1 [children] => ar...
Given the following two indexed arrays: $a = array('a', 'b', 'c'); $b = array('red', 'blue', 'green'); What is the most straighforward/efficient way to produce the following associative array?: $result_i_want = array('a' => 'red', 'b' => 'blue', 'c' => 'green'); Thanks. ...
In Visual Basic within STATISTICA (a stats program), I am trying to run "LOWESS," an existing STATISTICA Matrix Library Function. I have defined my arrays based on the number of rows and columns I either know or expect they should have. Unfortunately, my macro gets an error of "(10025) Array has different number of indexes" when runnin...
k = [1,2,3,4,5] for n in k puts n if n == 2 k.delete(n) end end puts k.join(",") # Result: # 1 # 2 # 4 # 5 # [1,3,4,5] # Desired: # 1 # 2 # 3 # 4 # 5 # [1,3,4,5] This same effect happens with the other array iterator, k.each: k = [1,2,3,4,5] k.each do |n| puts n if n == 2 k.delete(n) end end puts k.join(",") ha...
I am working on an algorithm in Python that uses arrays of int64s heavily. The arrays are typically sparse and are read from and written to constantly. I am currently using relatively large native arrays and the performance is good but the memory usage is high (as expected). I would like to be able to have the array implementation not ...
I have my menu button bringing up a Settings option, which brings up numerous ListPreferences such as weight and various sizes for glasses (it's a BAC calculator app). I'll pick one example... weight will work. Depending on how much you weigh it will affect your BAC. I have a int for Weight, set at 180. I would like someone to be able t...

READ FIRST: I have rewritten this question with the help of a friend to be hopefully more specific in what is required. It can be found here I'm not very clear on n-cubes, but I believe they are what I am referring to as the square family. New Question Wording: Perhaps I wasn't clear enough. What I'm asking, is how to set a 1D array to...
I have an array of GLuint with fixed size: GLuint textures[10]; Now I need to set a size of array dynamically. I wrote something like this: *.h: GLuint *textures; *.m: textures = malloc(N * sizeof(GLuint)); where N - needed size. Then it used like this: glGenTextures(N, &textures[0]); // load texture from image -(GLuint)ge...
I have an xml layout file which contains a few widgets including a Spinner I want to display a list of strings in the spinner, the list is generated at runtime as a result of a function so it can not be in arrays.xml. I tried doing: String[] SpinnerItems = GetMyCustomItems(); ((Spinner)findViewById(R.id.MySpinner)).setAdapter(new Ar...
You're given a big array with Integral type value, How do you move all zero values within it to the front portion of the array in a Time Efficiency way? e.g. 0,1,72,3,0,5,9,0,6,51,0,3 ---> 0,0,0,0,1,72,3,5,9,6,51,3 Regards! ...
If I can pass in an array of a known size: void fn(int(*intArray)[4]) { (*intArray)[0] = 7; } why can't I return one: int intArray[4] = {0}; int(*)[4] fn() { return &intArray; } here, the ")" in "(*)" generates "syntax error : )". ...
Hi There, I am trying to submit some data to a PHP script, however the PHP scripts expects the data to arrive in a specific format, like this example which is a dump of the post, Array ( [save] => Add to shortlist [cv_file] => Array ( [849709537] => Y [849709616] => Y [849709633] => Y ) ) The process is currently that a user selects t...
