  • Variable Scoping in a method and its persistence in C++

    - by de costo
    Consider the following public method that adds an integer variable to a vector of ints(private member) in a class in C++. KoolMethod() { int x; x = 10; KoolList.Add(x); } Vector<int>KoolList; But is this a valid addition to a vector ??? Upon calling the method, it creates a local variable. The scope of this local variable ends the moment the execution control leaves the method. And since this local variable is allocated on a stack(on the method call), any member of KoolList points to an invalid memory location in deallocated stack which may or may not contain the expected value of x. Is this an accurate description of above mechanism ?? Is there a need for creating an int in heap storage using "new" operator everytime a value needs to be added to the vector like described below ????: KoolMethod() { int *x = new int(); *x = 10; KoolList.Add(x); } Vector<int*>KoolList;

  • More compact way to do this?

    - by Macha
    I have a couple of functions that loop around the surrounding cells of a cell. The grid is contained inside an array. In my code, I have checks to make sure it's not one of the edge cells, as checking an undefined cell causes an error. As such, I have code like this: if(x > 0) { var firstX = x - 1; } else { var firstX = x; } if(x < 199) { var lastX = x + 1; } else { var lastX = x; } if(y > 0) { var firstY = y - 1; } else { var firstY = y; } if(y < 199) { var lastY = y + 1; } else { var lastY = y; } A lot of lines of code to do very little. Is there a more elegant way to do this?

  • Deleted array value still showing up on foreach loop in AS3 (bug in flash?)

    - by nexus
    It took me many hours to narrow down a problem in some code to this reproducible error, which seems to me like a bug in AVM2. Can anyone shed light on why this is occurring or how to fix it? When the value at index 1 is deleted and a value is subsequently set at index 0, the non-existent (undefined) value at index 1 will now show up in a foreach loop. I have only been able to produce this outcome with index 1 and 0 (not any other n and n-1). Run this code: package { import flash.display.Sprite; public class Main extends Sprite { public function Main():void { var bar : Array = new Array(6); out(bar); //proper behavior trace("bar[1] = 1", bar[1] = 1); out(bar); //proper behavior trace("delete bar[1]", delete bar[1]); out(bar); //proper behavior trace("bar[4] = 4", bar[4] = 4); out(bar); //for each loop will now iterate over the undefined position at index 1 trace("bar[0] = 0", bar[0] = 0); out(bar); trace("bar[3] = 3", bar[3] = 3); out(bar); } private function out(bar:Array):void { trace(bar); for each(var i : * in bar) { trace(i); } } } } It will give this output: ,,,,, bar[1] = 1 1 ,1,,,, 1 delete bar[1] true ,,,,, bar[4] = 4 4 ,,,,4, 4 bar[0] = 0 0 0,,,,4, 0 undefined 4 bar[3] = 3 3 0,,,3,4, 0 undefined 4 3

  • How to move positions within an array?

    - by Jade Mulholland
    A program that simply moves array elements. Two variables: userInputVariable and blankSpaceVariable. I have a 2D array named table. Defined as table[userInputVariable + 1][6] I am printing out this array in a table format, and the far left column is numbered by whatever number the user entered at the beginning of the program. I then ask the user where they would like to enter a blank space within the array. This blank space acts like a divider for all the other information in the array. For example, if the user enters 10 at the start for the userInputVariable, and then enters 5 for the blank space. Once printed, the numbers should go like this: 1, 2, 3, 4, --, 5, 6, 7, 8, 9, 10. My plan has been to create a for loop and try to move all the numbers in the array back a position starting from the blank space variable. What I currently have, but does not work: for (int i = blankSpaceVariable; i < table.length - 1; i++) { table[i] = table[i + 1]; } table[blankSpaceVariable] = "--"; With my current code, the numbers go like this: 1, 2, 3, 4, 6, 7, 8, 9, 10 Tried completing this a few different ways also, but the other info within my 2D array didn't move with the numbers. So I thought that this approach can hopefully move all the info within my 2D array down, and make way for a blank section. All help is greatly appreciated!

  • Java Double Array

    - by user1062058
    I'm having trouble setting up and placing values into an array using a text file containing the floating point numbers 2.1 and 4.3 each number is separated by a space - below is the error I'm getting: Exception in thread "main" java.util.NoSuchElementException import java.util.*; import java.io.*; public class DoubleArray { public static void main(String[] args) throws FileNotFoundException { Scanner in = new Scanner(new FileReader("mytestnumbers.txt")); double [] nums = new double[2]; for (int counter=0; counter < 2; counter++) { int index = 0; index++; nums[index] = in.nextDouble(); } } } Thanks, I'm sure this isn't a hard question to answer... I appreciate your time.

  • how to filter text of the selected value in drop down

    - by Carlos
    I have a drop down menu. Has product types. Product types have associated value (from drop down) values correspond to machine groups. So each option should have three variables--Machine name, values, machine group. I can get the Machine name and I can get the machine value (and display them in a different field)...what I have not been able to figure out is how to change the value into the Machine group. jQuery('#MachineName').bind('change', function() { //get selected value from drop down; var selectedValue = jQuery("#MachineName").val(); //populate a text field with the selected drop down value jQuery("#MachineValue").val(selectedValue); What I would like to do is keep that MachineValue but then populate another text field with the sorted MachineGroup I have been trying to run it through something like switch(jQuery(this).val()){ case "236" : newVal = "8"; break; But I don't want to "change" the value I just want to do an "if then" type filter, so maybe something like: '236' => "8", '237' => "5", I just don't know how to properly say "assign the MachineGroup based on the MachineValue" (and then have it populate a different text field) In the end I would have three fields. The drop down, the MachineValue and the MachineGroup. Drop down and value are done, I just need to do Group. (And I can sort Group based on MachineName...just not sure which would be easier)

  • PHP - Search array in array

    - by Anonymous2011
    I have tried googling for the past one hour straight now and tried many ways to search for an array, in an array. My objective is, to find a keyword in the URL, and the keywords are in a txt file. This is what i have so far - but doesn't work. $file = "keywords.txt"; $open = fopen($file,'r'); $data = fread($open,filesize($file)); $data = explode(" ",$data); $url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']; $url = parse_url($url); //parse the URL into an array foreach($data as $d) { if(strstr($d,$url)) { echo "yes"; } } This works WITHOUT the text file, or array - but that's not what i want. I'd appreciate it if anyone can assist me.

  • How do I generate an Array string from an array in memory (php).

    - by Itay Moav
    I need to create a big array in my code, I have the values in several tables (for easy management). I select it and now I have all the values in an array, in memory in the way I want. My problem, I need to write this array down, into the code. Is there a way to take an array which sits in the memory and translate it into a string "array('g'='h','b'='d'....)" which I can then echo and just copy-paste into my code?

  • Printing distinct integers in an array

    - by ???
    I'm trying to write a small program that prints out distinct numbers in an array. For example if a user enters 1,1,3,5,7,4,3 the program will only print out 1,3,5,7,4. I'm getting an error on the else if line in the function checkDuplicate. Here's my code so far: import javax.swing.JOptionPane; public static void main(String[] args) { int[] array = new int[10]; for (int i=0; i<array.length;i++) { array[i] = Integer.parseInt(JOptionPane.showInputDialog("Please enter" + "an integer:")); } checkDuplicate (array); } public static int checkDuplicate(int array []) { for (int i = 0; i < array.length; i++) { boolean found = false; for (int j = 0; j < i; j++) if (array[i] == array[j]) { found = true; break; } if (!found) System.out.println(array[i]); } return 1; } }

  • PHP array minor problem

    - by Sennheiser
    I'm really not sure how to explain this. It's so simple I can't fathom why it's not working. I have a loop. It puts a bunch of strings into an array. If I fill a single variable with any given string, it will output it perfectly. But filling an array with the strings will make it give me the dreaded: Array Array Array Array Array Array Array Array Note: my strings are not all 'Array'. The way I loop is: while(...) { $arr[] = $resultFromLoop; } Here is my var_dump. array(1) { ["tagName"]=> string(5) "magic" } array(1) { ["tagName"]=> string(4) "nunu" } array(1) { ["tagName"]=> string(5) "books" } array(1) { ["tagName"]=> string(0) "" } array(1) { ["tagName"]=> string(3) "zzz" } array(1) { ["tagName"]=> string(4) "grey" } array(1) { ["tagName"]=> string(3) "new" } array(1) { ["tagName"]=> string(6) "flight" }

  • What is the most efficient way to handle points / small vectors in JavaScript?

    - by Chris
    Currently I'm creating an web based (= JavaScript) application thata is using a lot of "points" (= small, fixed size vectors). There are basically two obvious ways of representing them: var pointA = [ xValue, yValue ]; and var pointB = { x: xValue, y: yValue }; So translating my point a bit would look like: var pointAtrans = [ pointA[0] + 3, pointA[1] + 4 ]; var pointBtrans = { x: pointB.x + 3, pointB.y + 4 }; Both are easy to handle from a programmer point of view (the object variant is a bit more readable, especially as I'm mostly dealing with 2D data, seldom with 3D and hardly with 4D - but never more. It'll allways fit into x,y,z and w) But my question is now: What is the most efficient way from the language perspective - theoretically and in real implementations? What are the memory requirements? What are the setup costs of an array vs. an object? ... My target browsers are FireFox and the Webkit based ones (Chromium, Safari), but it wouldn't hurt to have a great (= fast) experience under IE and Opera as well...

  • Read file structure into an array, but only specific files.

    - by dmackerman
    I have a directory structure that looks like this: /expandables - folder - folder - folder - folder - BannerInfo.txt - index.html Each one of the folder has the same exact stucture. One file named BannerInfo.txt and index.html. There are about 250 of these folders if that matters. I want to loop through these folders and store each of the index.html files into an array. Inside of the index.html file is just some simple HTML and Javascript of which I want to read into a string to be displayed later on. I'm struggling with how to filter out only the index.html file from the individual folders. The purpose of this is because I want to randomly select an index.html file and put the contents into a textarea. I thought I could do a simple array_rand() on the returned array and spit out the string. Any ideas?

  • 3x3 array = 10 numbers

    i have this code #include <math.h> #include <stdio.h> const int n = 3; const int s = 3; int getm(int mat[n][s]); int printm(int mat[n][s]); int main() { int m[n][s]; getm(m); printm(m); return 0; } int getm(int mat[n][s]) { for(int x = 0;x < n;x++) { for (int y = 0;y<s;y++) { scanf("%i ", &mat[x][y]); } } return 0; } int printm(int mat[n][s]) { for(int x = 0;x<n;x++) { for(int y = 0;y<s;y++) { printf("%i ", mat[x][y]); if(y==(s-1)) { printf("\n"); } } } } which shoud ask for 9 numbers to make a 3x3 matrix array, but it actually asks for 10 numbers, printm is working well - printing only 9 numbers. Where is error?
