I have the code to read in the file and print it out, but dont know how to take each int. I think i need to splitstring method and a blank delimiter "" in order to take every charcter, but after that im not sure. I would ...

The following is the problem I'm working on and my snippet of code. Is there a better way to implement this? I have used basic control structures for this below. Is it better to store the rows and columns in a map and searching through the map based on the key/value pairs? There is a security keypad at the entrance of a building. It...

I found that accessing Dictionary and Multi-Dimension array can be slow-- quite a puzzle since access time for dictionary and array is O(1). This is my code public struct StateSpace { public double q; public double v; public double a; } public class AccessTest { public Dictionary<int, Dictionary<double,StateSpace>> ModeStateSpace; ...
I have a multi-dimensional array generated in PHP: array( 'Requirements' => array( 'export_requirements' => array('value'=> 1, 'label'=> 'Export'), 'add_requirements' => array('value'=> 2, 'label'=> 'Add'), 'add_private_requirements' => array('value'=> 4, 'label'=> 'Add Private...

I need to get the length of a 2D array for both the row and column. I’ve successfully done this, using the following code: public class MyClass { public static void main(String args[]) { int[][] test; test = new int[5][10]; int row = test.length; int col = test[0].length; System.out.println(row); System.out.println...
Hi, So Im working on a Excel xml parsing class, and Im trying to search through an array of the header values of the file, to return the key integer. If I can get the key int, then I can grab an entire column by the value of the header in the file. I have tried using in_array, search_array and a bunch of other functions, but nothing is ...
I'm trying to build a navigation menu. I am receiving an array with a structure like this: [ [ Title = A Sub items = [ Title = B Sub items = [ Title = C ] ] ], [ Title = A Sub items = [ Title = B Sub items = [ Title = D ] ] ], ] I need to take it and ...
How can I add arrays into an existing array item? For instance: $user[$user->id] = array(//values); But if that user needs another array added, I want all data to fall under that user ID in the array. I want to store orders a user has made, so I can look up all orders on the fly by user ID in the $user array above. ...
This: bool grid[1280][1024]; for (int x = 0; x<1280; x++) { for (int y = 0; y<1024; y++) { grid[x][y] = false; } } works fine, but bool grid[1280][1024]; bool grid2[1280][1024]; for (int x = 0; x<1280; x++) { for (int y = 0; y<1024; y++) { grid[x][y] = false; grid2[x][y] = false; } } ...
I've got a list of 400 numbers, and i want to but them in a 20x20 grid using Python. I've made a "2d array" (not really because Python doesn't support them, I've had to use a list of lists.) When i try to loop through and assign each subsequnt item to the next box in the grid, it fails. i end up assinging the last item in the list to ...
I have a method which returns a array of ByteArray: public byte[][] Draw(ImageFormat imageFormat, ImageSize imageSize); and I need to write it into a MemoryStream: var byteArray = instanceName.Draw(ImageFormat.Jpeg, ImageSize.Dpi150); MemoryStream ms = new MemoryStream(byteArray[0]); This is working so far because the array of byte...
Hi there, Excuse the newbie question. I'm trying to create a two dimensional array in ruby, and initialise all its values to 1. My code is creating the two dimensional array just fine, but fails to modify any of its values. Can anyone explain what I'm doing wrong? def mda(width,height) #make a two dimensional array a = Ar...
I'm trying to implement dynamically allocated contiguous 3D arrays in a C code. The arrays must be contiguous because I'm relying on netCDF output of the arrays. Now I adapted a solution posted here Stack OverFlow Solution. This works fine for dynamically allocating the arrays and indexing them...however, when netCDF outputs them ther...
Hello, I have this line of string Fruits-banana|apple|orange:Food-fries|sausages:Desserts-ice cream|apple pie the : (colon) is the separator for the main topic, and the | is the separator for the different type of sub topics. I tried to explode it out and put it into array, I need the result to be something like this to be displayed...
I haven't used C in 5-6 years, and feel that this is probably a really obvious answer. I thought that arrays were passed by reference automatically in C, so my code below should modify the values of the array created in main() within the change function. It changes the values of the local variable within the change function, but this is...
private void equal_AxB() { int x = matrix_A.length; int y = matrix_B[0].length; matrix_C = new double[x][y]; for(int i = 0; i < x; i++) { for(int j = 0; j < y; j++) { for(int k = 0; k < y; k++){ matrix_C[i][j] += matrix_A[i][k]*matrix_B[k][j]; } } } return; ...
