  • Finding unique elements in an string array in C

    - by LuckySlevin
    Hi, C bothers me with its handling of strings. I have a pseudocode like this in my mind: char *data[20]; char *tmp; int i,j; for(i=0;i<20;i++) { tmp = data[i]; for(j=1;j<20;j++) { if(strcmp(tmp,data[j]))//then except the uniqueness, store them in elsewhere. } } But when i coded this the results were bad.(I handled all the memory stuff,little things etc.) The problem is in the second loop obviously :D. But i cannot think any solution. How do i find unique strings in an array. Example input : abc def abe abc def deg entered unique ones : abc def abe deg should be found.

  • Moving a Ball on iPhone

    - by Chandan Shetty SP
    I am using below formula to move the ball circular, where accelX and accelY are the values from accelerometer, it is working fine. But the problem in this code is mRadius(I fixed its value to 50), i need to change mRadius according to accelerometer values and also i need bouncing effect when it touches other circles please send your answers ASAP... I am waiting. float degrees = -atan2(accelX, accelY) * 180 / 3.14159; int x = cCentrePoint.x + mRadius * cos(degreesToRadians(degrees)); int y = cCentrePoint.y + mRadius * sin(degreesToRadians(degrees)); Here is the snap of the game i want to develop. http://iphront.com/wp-content/uploads/2009/12/bdece528ea334033.jpg.jpg

  • Transfer of control and data between C and C#

    - by Prithvi
    C# main program needs to call a C program GA.c This C code executes many functions and one function initialize() calls objective() function. But this objective function needs to be written in C#.This call is in a loop in the C code and the C code needs to continue execution after the return from objective() until its main is over and return control to C# main program. C# main() { //code call to GA in C; //remaining code; } GA in C: Ga Main() { //code call to initialize function(); //remaining code } initialize funtion() in GA { for(some condition) { //code call to objective(parameter) function in C#; //code } } How do we do this?

  • listview tile layout problem (vb.net)

    - by Matt Facer
    hi guys, I have a listview which displays (eventually) an album cover of an itunes play list with the album name under it. the problem I am having is that I cannot get the album art (currently a blank square) ABOVE the album name. It always is on the side... how do I do it? I've tried adding column headers and alsorts... code to set up the listview Dim myImageList As ImageList albumList.View = View.Tile albumList.TileSize = New Size(120, 150) ' Initialize the item icons. myImageList = New ImageList() myImageList.Images.Add(Image.FromFile("c:/test.jpg")) myImageList.ImageSize = New Size(80, 80) albumList.LargeImageList = myImageList I then do a loop to display each album name which uses Dim item0 As New ListViewItem(New String() _ {Albums(i).Name}, 0) albumList.Items.Add(item0) the output is http://i111.photobucket.com/albums/n122/mfacer/Screenshot2010-05-02at164815.png but as i said, I want the album name under the orange box.... any ideas?? Thanks for any info!

  • Why won't the following Clojure code tail a file via ssh?

    - by Zubair
    The following code never manages to tail a file. It simply hangs waiting for reader input. Has anyone tried anything similar? (def output (ref [] )) (import 'ch.ethz.ssh2.Connection) (import 'ch.ethz.ssh2.Session) (import 'ch.ethz.ssh2.StreamGobbler) (import 'java.lang.StringBuilder) (import 'java.io.InputStream) (import 'java.io.BufferedReader) (import 'java.io.InputStreamReader) (let [connection (new Connection "hostname")] (. connection connect) (let [ok (. connection authenticateWithPassword "username" "password" ) session (. connection openSession )] (. session execCommand "tail -f filename.txt") (let [sb (StringBuilder.) stdout (StreamGobbler.

  • attaching id to a movieclip

    - by Ross
    I have a loop that creates mc from a database for (var i:Number = 0; i < t.length; i++) { var portfolioItem:PortfolioItem = new PortfolioItem(); addChild(portfolioItem); portfolioItem.name = t[i][0]; portfolioItem.addEventListener(MouseEvent.CLICK, getThisName); } public function getThisName(evt:Event) { trace(evt.target.name); } I try and assign t[i][0] which is the table id to the name attribute but I jsut get 'instance4' or instance 14. How can I give these dynamically create mc's a name or custom property? ideally I would like to use a custom property called portfolio.id but would use the name property or another default property if it works.

  • Optional structural typing possibilty in C++ or anyother language?

    - by ambhai
    In C++ how to tell compiler that Ogre::Vector3 IS_SAME_AS SomeOtherLIB::Vector3 ? I feel that.. in languages like c++ which are not structural typed but there are cases when it makes sense. Normally as game developer when working with 4+ libraries that provide sort or their own Vector3 implementation. The code is littered with ToOgre, ToThis, ToThat conversion function. Thats a lot of Float3 copying around which should not happen on first place. Is in C++ or any other languages where we dont have to convert (copying) from one type to another which is essentially the samething. But any solution in C++ as most of the good gamedevs libs are for c/c++.

  • How to output an array's content in columns in BASH.

    - by Arko
    I wanted to display a long list of strings from an array. Right now, my script run through a for loop echoing each value to the standard output: for value in ${values[@]} do echo $value done Yeah, that's pretty ugly! And the one column listing is pretty long too... I was wondering if i can find a command or builtin helping me to display all those values in columns, like the ls command does by default when listing a directory (ls -C). [Update] Losing my brain with column not displaying properly formatted columns, here's more info: The values: $ values=( 01----7 02----7 03-----8 04----7 05-----8 06-----8 07-----8 08-----8 09---6 10----7 11----7 12----7 13----7 14-----8 15-----8 16----7 17----7 18---6 19-----8 20-----8 21-----8) (Notice the first two digits as an index and the last one indicating the string length for readability) The command: echo " ${values[@]/%/$'\n'}" | column The result: Something is going wrong...

  • Posting null values via AJAX

    - by nickf
    Using the jQuery $.post function, if you send a null value, it arrives at the server side as "null". Example: Javascript: $.post('test.php', { foo : null }); PHP: var_dump($_POST['foo']); // string(4) "null" I understand why this is so, but was wondering the best way to work around the limitation? Should you: Loop through all the variables in JS before you send them and replace with an empty string? Interpret "null" as null on the server side? Don't send the variable at all? Something else?

  • Leak caused by fread

    - by Jack
    I'm profiling code of a game I wrote and I'm wondering how it is possible that the following snippet causes an heap increase of 4kb (I'm profiling with Heapshot Analysis of Xcode) every time it is executed: u8 WorldManager::versionOfMap(FILE *file) { char magic[4]; u8 version; fread(magic, 4, 1, file); <-- this is the line fread(&version,1,1,file); fseek(file, 0, SEEK_SET); return version; } According to the profiler the highlighted line allocates 4.00Kb of memory with a malloc every time the function is called, memory which is never released. This thing seems to happen with other calls to fread around the code, but this was the most eclatant one. Is there anything trivial I'm missing? Is it something internal I shouldn't care about? Just as a note: I'm profiling it on an iPhone and it's compiled as release (-O2).

  • .htaccess rewrite subdomains

    - by Cyclone
    Here is my current code: RewriteCond %{HTTP_HOST} !^example\.com [NC] #RewriteCond %{REQUEST_URI}!^something RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com RewriteRule (.*) something/%1/$1 [QSA,L] My goal is to rewrite http://*.example.com/whatever to http://example.com/something/*/whatever, assuming * is the same for both and whatever is the same for both. However, I believe this is causing an infinite loop somehow, so I added that commented out line (RewriteBase is / btw), but if I uncomment then the entire site is a 500 response code. Without that line, only the subdomains error. What am I doing wrong, and how can I fix this? I have already configured the server so anything gets redirected to my public_html folder. EDIT: For clarification, I am trying to do an internal redirect, not external. EDIT: There is not a flag for internal redirect it seems. Is there any place I can see the actual error message for the broken rewriterule? If I knew what was wrong I would be able to stand a better chance of fixing it.

  • How Do I Pass The Value (Not The Reference) of a JS Variable to a Function?

    - by ryan
    Here is a simplified version of something I'm trying to run: for (var i = 0; i < results.length; i++) { marker = results[i]; google.maps.event.addListener(marker, 'click', function() { change_selection(i); }); } but I'm finding that every listener uses the value of results.length (the value when the for loop terminates). How can I add listeners such that each uses the value of i at the time I add it, rather than the reference to i?

  • Monitor and Terminate Python script based on system resource use

    - by Vincent
    What is the "right" or "best" way to monitor the system resources a python script is using and terminate it if the resource use exceeds some predetermined values. In my case memory usage is of concern. I am not asking how to measure the system resource use although I am open to suggestions. As a simple example, let's assume I have a function that finds prime numbers less than some large number and adds them to a list based on some condition. I don't know ahead of time how many prime numbers will satisfy the condition so I what to be sure to terminate the function if I use up to much system memory (8gb lets say). I know that there are ways to monitor the size of python objects. What I don't know is the proper way to monitor the size of the list and exit is to just include a size test in the prime function loop and exit if it exceeds 8gb or if there is an "external" way to monitor and exit.

  • Creating a loading screen in HTML5

    - by espais
    I am having some issues finding a decent tutorial for generating a loading style screen with regards to HTML5. To be quite honest I'm not sure exactly where to begin... My project is essentially a simple HTML5 game, where I'll be loading in various sprite sheets and tilesets. They'll be reasonably small, but I'd like to show a little loading spinner instead of a blank screen while all the resources are loaded. Much appreciated if somebody could point me in the right direction, be it decent links or code samples to get me going...my Google-fu is lacking today! For clarification, I need to figure out how to load the resources themselves, as opposed to finding a spinner. For instance, how to calculate that X% has loaded.

  • combining dynamic text with regular expressions in php

    - by pfunc
    I am experimenting with finding popular keywords using curl, php and regular expressions. I have an array of non-specific nouns that I am matching my keyword search up. So I am looking for words like "the", "and", "that" etc. and taking them out of the keyword search. so I have an array of words like so: $wordArr = [the, and, at,....]; and then running something like: && preg_match('(\bmyword\w*\b)', $key) == false how do I combine these two so it loops through the array finding out if any of the words in the array match the regular expression? I guess I could just do a for loop, but though maybe I could use in_array($wordArr, $key).. or something like that.

  • How to calculate 2^n-1 efficiently without overflow?

    - by Ludwig Weinzierl
    I want to calculate 2^n-1 for a 64bit integer value. What I currently do is this for(i=0; i<n; i++) r|=1<<i; and I wonder if there is more elegant way to do it. The line is in an inner loop, so I need it to be fast. I thought of r=(1ULL<<n)-1; but it doesn't work for n=64, because << is only defined for values of n up to 63.

  • How can I create a simple message box in Python?

    - by Carson Myers
    I'm looking for the same effect as alert() in JavaScript. I wrote a simple web-based interpreter this afternoon using Twisted.web. You basically submit a block of Python code through a form, and the client comes and grabs it and executes it. I want to be able to make a simple popup message, without having to re-write a whole bunch of boilerplate wxPython or TkInter code every time (since the code gets submitted through a form and then disappears). I've tried tkMessageBox: import tkMessageBox tkMessageBox.showinfo(title="Greetings", message="Hello World!") but this opens another window in the background with a tk icon. I don't want this. I was looking for some simple wxPython code but it always required setting up a class and entering an app loop etc. Is there no simple, catch-free way of making a message box in Python?

  • Creating matrix of maximum values indices in MATLAB

    - by Gacek
    Using MATLAB, I have an array of values of size 8 rows x N columns. I need to create a matrix of the same size, that counts maximum values in each column and puts 1 in the cell that contains maximum value, and 0 elsewhere. A little example. Lets assume we have an array of values D: D = 0.0088358 0.0040346 0.40276 0.0053221 0.017503 0.011966 0.015095 0.017383 0.14337 0.38608 0.16509 0.15763 0.27546 0.25433 0.2764 0.28442 0.01629 0.0060465 0.0082339 0.0099775 0.034521 0.01196 0.016289 0.021012 0.12632 0.13339 0.11113 0.10288 0.3777 0.19219 0.005005 0.40137 Then, the output matrix for such matrix D would be: 0 0 1 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 1 Is there a way to do it without catching vector of indices from max function and then putting ones in the right place using for loop?

  • Get positions for NAs only in the "middle" of a matrix column

    - by Abiel
    I want to obtain an index that refers to the positions of NA values in a matrix where the index is true if a given cell is NA and there is at least one non-NA value before and after it in the column. For example, given the following matrix [,1] [,2] [,3] [,4] [1,] NA 1 NA 1 [2,] 1 NA NA 2 [3,] NA 2 NA 3 the only value of the index that comes back TRUE should be [2,2]. Is there a compact expression for what I want to do? If I had to I could loop through columns and use something like min(which(!is.na(x[,i]))) to find the first non-NA value in each column, and then set all values before that to FALSE (and the same for all values after the max). This way I would not select leading and trailing NA values. But this seems a bit messy, so I'm wondering if there is a cleaner expression that does this without loops.

  • Find next lower item in a sorted list

    - by Sebastian
    Hey guys, let's say I have a sorted list of Floats. Now I'd like to get the index of the next lower item of a given value. The usual for-loop aprroach has a complexity of O(n). Since the list is sorted there must be a way to get the index with O(log n). My O(n) approach: index=0 for i,value in enumerate(mylist): if value>compareValue: index=i-1 Is there a datatype for solving that problem in O(log n)? best regards Sebastian

  • Method of getting text on a windows form ( unmanaged C++ project )

    - by Donovan
    I'm in the process of learning C++. I've created a boilerplate Win32 app within VC++ 2008. I've studied through the code and am ready do do a bit of experimenting. I thought it would be cool to print all the windows messages received in the message loop to the form created via the boilerplate code. I for the life of me, can't figure out the method of getting text onto that form. I can't seem to identify and named object that I can use to reference that damn form. The best I can figure is I need to use the handle to reference the form somehow. Still, even if I did know how to reference the form, I'm not sure I know how I would create a label to display the text. Anyway, if someone could just point out what methodology I need to learn to make this happen it would be much appreciated. Thanks, Donovan

  • Distance between numpy arrays, columnwise

    - by Jaapsneep
    I have 2 arrays in 2D, where the column vectors are feature vectors. One array is of size F x A, the other of F x B, where A << B. As an example, for A = 2 and F = 3 (B can be anything): arr1 = np.array( [[1, 4], [2, 5], [3, 6]] ) arr2 = np.array( [[1, 4, 7, 10, ..], [2, 5, 8, 11, ..], [3, 6, 9, 12, ..]] ) I want to calculate the distance between arr1 and a fragment of arr2 that is of equal size (in this case, 3x2), for each possible fragment of arr2. The column vectors are independent of each other, so I believe I should calculate the distance between each column vector in arr1 and a collection of column vectors ranging from i to i + A from arr2 and take the sum of these distances (not sure though). Does numpy offer an efficient way of doing this, or will I have to take slices from the second array and, using another loop, calculate the distance between each column vector in arr1 and the corresponding column vector in the slice?

  • Split number and put each digit to separate html element

    - by Seven
    The problem is that I do not know how to break the loop for the first number and start again for the next one. Currently, one span.nNumber has a total digits of the two numbers (123456) and the next span.nNumber contains digits only from another number (456). Goal is to create sequence 123 and 456: <span class='nNumber'> <span>1</span> <span>2</span> <span>3</span> </span> and <span class='nNumber'> <span>4</span> <span>5</span> <span>6</span> </span> Example script: http://jsfiddle.net/PZ8Pt/2/
