  • Finding character in String in Vector.

    - by SoulBeaver
    Judging from the title, I kinda did my program in a fairly complicated way. BUT! I might as well ask anyway xD This is a simple program I did in response to question 3-3 of Accelerated C++, which is an awesome book in my opinion. I created a vector: vector<string> countEm; That accepts all valid strings. Therefore, I have a vector that contains elements of strings. Next, I created a function int toLowerWords( vector<string> &vec ) { for( int loop = 0; loop < vec.size(); loop++ ) transform( vec[loop].begin(), vec[loop].end(), vec[loop].begin(), ::tolower ); that splits the input into all lowercase characters for easier counting. So far, so good. I created a third and final function to actually count the words, and that's where I'm stuck. int counter( vector<string> &vec ) { for( int loop = 0; loop < vec.size(); loop++ ) for( int secLoop = 0; secLoop < vec[loop].size(); secLoop++ ) { if( vec[loop][secLoop] == ' ' ) That just looks ridiculous. Using a two-dimensional array to call on the characters of the vector until I find a space. Ridiculous. I don't believe that this is an elegant or even viable solution. If it was a viable solution, I would then backtrack from the space and copy all characters I've found in a separate vector and count those. My question then is. How can I dissect a vector of strings into separate words so that I can actually count them? I thought about using strchr, but it didn't give me any epiphanies.

    Hello, I am following these steps in order to build Awesome window manager on 10.04 I am building 3.4 while the tutorial is for 3.1 I installed all of the specified dependencies including cairo.

  • How to loop through columns in an oracle pl/sql cursor.

    - by Lloyd
    I am creating a dynamic cursor and I would like to loop over the columns that exist in the cursor. How would I do that? For example: create or replace procedure dynamic_cursor(empid in varchar2, RC IN OUT sys_refcursor) as stmt varchar2(100); begin stmt := 'select * from employees where id = ' || empid; open crs for stmt using val; for each {{COLUMN OR SOMETHING}} --TODO: Get this to work loop; end;

  • How to organize infinite while loop in SQL Server ?

    - by alpav
    I want to use infinite WHILE loop in SQL Server 2005 and use BREAK keyword to exit from it on certain condition. while true does not work, so I have to use while 1=1. Is there a better way to organize infinite loop ? I know that I can use goto, but while 1=1 begin .. end looks better structurally.

  • How to create a new background process in a KSH "while read" loop?

    - by yael
    The following test script has a problem. When I add the line (sleep 5 ) & in the script then the "while read" loop does not read all lines from the file, but only prints the first line. But when I remove the ( sleep 5 ) & from the script, then the script prints all lines as defined in the file. Why the ( sleep 5 ) & causes this? And how to solve the problem? I want to create a new process (for which the sleep is just an example) in the while loop: $ more test #!/bin/ksh while read -r line ; do echo Read a line: echo $line ( sleep 5 )& RESULT=$! echo Started background sleep with process id $RESULT sleep 1 echo Slept for a second kill $RESULT echo Killed background sleep with process id $RESULT done < file echo Completed On my Linux, when using the following contents of file: $ more file 123 aaa 234 bbb 556 ccc ...running ./test just gives me: Read a line: 123 aaa Started background sleep with process id 4181 Slept for a second Killed background sleep with process id 4181 Completed

  • Can't install Hyper-V in Windows 8 Pro. Causes boot loop, pain & suffering

    - by Nick
    Hardware: Intel i7 2600K (not overclocked, SLAT compatible, virt. features enabled in bios) Asus Maximus IV Extreme-Z (Z68) 16Gb RAM 256Gb SSD Other non-trivial working parts Adding Hyper-V is causing a boot loop resulting in an attempt at automatic repair by Windows 8 after the second or third loop: I'm trying to get the Windows Phone 8 SDK installed and I've narrowed down my troubles to the Hyper-V feature in Win8. This is required to run the WP8 emulator and there are no install options to omit this feature. My first attempt completely borked the OS as I did not have a recent restore point or system image, so I did a completely clean install and made plenty of backups/restore points. I skipped the SDK install and went straight for the windows feature add-on for Hyper-V. This confirmed that Hyper-V is the issue as the same behavior resulted. I cannot find any hint in the Event Logs. Cancelling automatic recovery causes the same behavior to repeat. I don't have any other VM products installed. My only recourse is to use a restore point, try something else, install it again, and see what happens. No luck so far. I'm on my 10th attempt here. Any help would be much appreciated.

  • How do I find and kill a php loop (process)?

    - by Hoytman
    I have a php script that I have been developing which calls an external api within a loop. It is being tested on a VPS which is running LAMP on Debian. I noticed this morning that the api was not responding to my script. When I called the provider, they told me that my server had been calling the api 1000's of times per hour for the past 10 hours. I am assuming that a php script (which I have been working on the day before and testing on my VPS) entered into an infinite loop during one of the executions, and never came out (I have been testing it from the command prompt, and not over the web.) I have attempted to stop and start Apache, but the api support staff says that the calls are still coming in from my server address. How can I find and stop the process? Also, is there a possibility that the Apache stop/start solved the problem, but the api is still trying to sort through past calls? Please forgive me for not using my local test environment correctly. Edit: I do not know the process name, I need to discover the name (or pid) based on behavior.

  • Ubuntu 11.10 - How can i stop self-feedback-loop, coming directly from my microphone to speaker?

    - by YumYumYum
    I have microphone audio, which comes instantly to my speaker. I am using default pulseaudio and alsa from the package. I have tried to setup: 1) PA /etc/pulse/default.pa /etc/asound.conf $ ls analog-input-aux.conf analog-input-fm.conf analog-input-mic.conf analog-input-tvtuner.conf analog-output-desktop-speaker.conf analog-output-mono.conf analog-input.conf analog-input-front-mic.conf analog-input-mic.conf.common analog-input-video.conf analog-output-headphones-2.conf analog-output-speaker.conf analog-input.conf.common analog-input-internal-mic.conf analog-input-mic-line.conf analog-output.conf analog-output-headphones.conf iec958-stereo-output.conf analog-input-dock-mic.conf analog-input-linein.conf analog-input-rear-mic.conf analog-output.conf.common analog-output-lfe-on-mono.conf 2) ALSA in lsmod to make sure no loopback modules are loaded etc but none is resolving it. And there are many less information available on this. Has anyone similar problem solution in Ubuntu 11.10? (this problem i have resolved in Ubuntu 11.04 by replacing the default pulseaudio version to latest source from git, but while trying the same in Ubuntu 11.10 does not worked). Any tips please?

  • where to define variable for a for each loop?

    - by David
    can you please advise me why my first code attempt didn't work : public void listAllFiles() { for(String filename : files) { int position = 0; System.out.println(position + ": " + filename); position = position + 1; } } it kept printing position at 0 without iterating position but it seems to work after i did it this way: public void listAllFiles() { int position = 0; for(String filename : files) { System.out.println(position + ": " + filename); position = position + 1; } } I don't understand why the position + 1 was not being executed, is it because we are not meant to define variables inside for loops or am i missing something in my code.

  • Why do most of us use 'i' as a loop counter variable?

    - by kprobst
    Has anyone thought about why so many of us repeat this same pattern using the same variable names? for (int i = 0; i < foo; i++) { // ... } It seems most code I've ever looked at uses i, j, k and so on as iteration variables. I suppose I picked that up from somewhere, but I wonder why this is so prevalent in software development. Is it something we all picked up from C or something like that? Just an itch I've had for a while in the back of my head.

  • How to debug a fatal system crash - [graphical loop DOTA2]?

    - by Huw
    Whilst playing DOTA2, I occasionally and apparently randomly seem to be experiencing a fatal crash where the display freezes fixed and the audio loops over approx the last .5 of a second. Now, I'm interested in resolving this - but my trouble is I don't know where to start. The error appears non-reproducible (I've tried returning to games and deploying the same combination of events in hopes of pinning to to a certain shader etc), and I don't know which part of 'the stack' it might be coming from. Variables that occur to me: I custom build this system, did I do something wrong - is my PSU not providing enough power to the graphics card? I am running Steam and DOTA under Linux, could this new software have a bug Might it be something to do with my ATI Catalyst graphics drivers Is some other background process interfering I'm usually mid game when this occurs, so i quickly kill the power and reboot (when i'm lucky i can get back in with only 1-2 mins lost!). So my question here relates to logs. Where should I start to look or how might I set up logs to help me pin down a fatal crash of this kind by recording moments up to / before a crash and is this likely to be something I should push Steam to do, or is there something at a system level? Then perhaps I can return with a more specific question and perhaps even a bug report :) Many thanks in advance.

  • Why do most of us use 'i' as a loop counter variable?

    - by kprobst
    Has anyone thought about why so many of us repeat this same pattern using the same variable names? for (int i = 0; i < foo; i++) { // ... } It seems most code I've ever looked at uses i, j, k and so on as iteration variables. I suppose I picked that up from somewhere, but I wonder why this is so prevalent in software development. Is it something we all picked up from C or something like that? Just an itch I've had for a while in the back of my head.

  • Variable-step update() in game loop is falling behind, how can I get around this?

    - by ThatsGobbles
    I'm working on a minimal game engine for my next game. I'm using the delta update method like shown: void update(double delta) { // Update code that uses `delta` goes here } I have a deep hierarchy of updatable objects, with a root updatable that contains several updatables, each of which contains more updatables, etc. Normally I'd just iterate through each of the root's children and update each one, which would then do the same for its children, and so on. However, passing a fixed value of delta to the root means that by the time the leaf updatables are reached, it's been longer since delta seconds that have elapsed. This is causing noticable desyncing in my game, and time synchronization is very important in my case (I'm working on a rhythm game). Any ideas on how I should tackle this? I've considered using StopWatches and a global readable timer, but any advice would be helpful. I'm also open to moving to fixed timesteps as opposed to variable.

  • Spring mvc: controller returns [][], usable in jsp with foreach, but how to bind?

    - by Joe
    I'm building a spring mvc application. Now the problem I have is the following. I have a controller which adds a DayInfo[][] to my ModelMap. (DayInfo has an id, a title (String) and Text(also String). Now the problem I have is that I have no problem displaying this DayInfo[][] with foreach tags in my jsp. However I'm outputting the Title property as an input box(type text), and I'd like to be able to update this value (and thus saving it to be a database but that shouldn't be a problem). However I'm having trouble with binding this value to the input box so that it is actually returned to the controller. If anyone has some advice it would be welcome.

    - by helle
    Hello Guys, i'm new with Codeigniter,and whish to know if i can access any kind of iterator for the foreach with {}-Notation in my views. The thing is, i'm having a list which should be devided after each x items. example (what i would like to do: <ul> {list} <li>{items}</li> <? if ($iterator % 15 == 0) echo "</ul><ul>"; ?> {/list} </ul> thanks in advice ;-)

  • How does Array.ForEach() compare to standard for loop in C#?

    - by DaveN59
    I pine for the days when, as a C programmer, I could type: memset( byte_array, '0xFF' ); and get a byte array filled with 'FF' characters. So, I have been looking for a replacement for this: for (int i=0; i < byteArray.Length; i++) { byteArray[i] = 0xFF; } Lately, I have been using some of the new C# features and have been using this approach instead: Array.ForEach<byte>(byteArray, b => b = 0xFF); Granted, the second approach seems cleaner and is easier on the eye, but how does the performance compare to using the first approach? Am I introducing needless overhead by using Linq and generics? Thanks, Dave
