  • Retrieve the Value of An Integer Variable

    - by Abluescarab
    This is probably easily figured out (I feel very stupid right now), but I can't find a solution anywhere, for some reason. Perhaps I'm not searching for the right thing. And maybe it's in some beginner tutorial I haven't watched. Anyway, I was wondering how to retrieve the value of an integer variable in C++? I know you can use cin.getline() for string variables, but I received an error message when I attempted that with an integer variable (and rightfully so, I know it was wrong, but I was looking for a solution). My project is a Win32 console application. What I'm trying to do is ask a user to input a number, stored in the variable n. Then I take the value of n and perform various math functions with it. In my header file, I have string, windows, iostream, stdio, math, and fstream. Do I need to add another library? There's not much more to tell. I can post my code if I must. EDIT: cout << "TEST SINE"; cout << "\nPlease enter a number.\n\n"; cin >> n; break; Here's the code I'm trying to use. Is this all I need to do? If so, how do I incorporate the variable so I can test it using sin, cos, and tan? Yet again, thanks ahead of time.

  • javascript watching for variable change via a timer

    - by DA
    I have a slide show where every 10 seconds the next image loads. Once an image loads, it waits 10 seconds (setTimeout) and then calls a function which fades it out, then calls the function again to fade in the next image. It repeats indefinitely. This works. However, at times, I'm going to want to over-ride this "function1 call - pause - function2 call - function1 call" loop outside of this function (for instance, I may click on a slide # and want to jump directly to that slide and cancel the current pause). One solution seems to be to set up a variable, allow other events to change that variable and then in my original function chain, check for any changes before continuing the loop. I have this set up: var ping = 500; var pausetime = 10000; for(i=0; i<=pausetime; i=i+ping){ setTimeout(function(){ console.log(gocheckthevariable()); console.log(i); pseudoIf('the variable is true AND the timer is done then...do the next thing') },i) } The idea is that I'd like to pause for 10 seconds. During this pause, every half second I'll check to see if this should be stopped. The above will write out to the console the following every half second: true 10000 true 10000 true 10000 etc... But what I want/need is this: true 0 true 500 true 1000 etc... The basic problem is that the for loop executes before each of the set timeouts. While I can check the value of the variable every half second, I can't match that against the current loop index. I'm sure this is a common issue, but I'm at a loss what I should actually be searching for.

  • linux bash script: set date/time variable to auto-update (for inclusion in file names)

    - by user1859492
    Essentially, I have a standard format for file naming conventions. It breaks down to this: target_dateUTC_timeUTC_tool So, for instance, if I run tcpdump on a target of 'foo', then the file would be foo_dateUTC_timeUTC_tcpdump. Simple enough, but a pain for everyone to constantly (and consistently) enter... so I've tried to create a bash script which sets system variables like so: FILENAME=$TARGET\_$UTCTIME\_$TOOL Then, I can just call the variable at runtime, like so: tcpdump -w $FILENAME.lpc All of this works like a champ. I've got a menu-driven .sh which gives the user the options of viewing the current variables as well as setting them... file generation is a breeze. Unfortunately, by setting the date/time variable, it is locked to the value at the time of creation (naturally). I set the variable like so: UTCTIME=$(/bin/date --utc +"%Y%m%d_%H%M%Z") What I really need is either a way to create a variable which updates at runtime, or (more likely) another way to skin this cat. While scouring for solutions, I came across a similar issues... like this. But, to be honest, I'm stumped on how to marry the two approaches and create a simple, distributable solution. I can post the entire .sh if anyone cares to review (about 120 lines)

  • skipping a variable using while read in bash

    - by Aleksandar Ivanisevic
    i'm reading a few variables from a file using while read a b c; do (something) done < filename is there an elegant way to skip a variable (read in an empty value), i.e. if I want a=1 b= c=3, what should I write in the file? Right now i'm putting 1 "" 3 and then use b=$(echo $b | tr -d \" ) but this is pretty cumbersome, IMHO any ideas?

  • how do I get vim home directory?

    - by nsharish
    I wanted to set VIMHOME variable this way(common to windows and linux), let $VIMHOME=expand("%:p")."/..", so that VIMHOME is "~/.vim" in linux or "path/to/vimfiles" in windows. I put this in a var.vim file and placed this in the plugin directory. It loads properly, but VIMHOME is set only to "./..". How do I get the full path of a file using expand? Is there an easy way to set VIMHOME?

  • Escaping Variable in Cat

    - by Peter
    I'm trying to write a shell script over ssh via a bash prompt. The shell, however, insists on interpreting any variable I want to write instead of writing it directly to file. For example, cat <<EOF >checkup.sh\n'$command'EOF is simply written as '' to file. How do I get $command written instead? I've tried every practical method of escaping I can think of. If it changes anything, I'm doing it over PHP using phpseclib.

  • How do I change Jenkins-ci systemInfo PATH variable

    - by Thomas Schultz
    I have Jenkins setup and it was working but then I updated java and now Jenkins acts like it doesn't know where it is. When I goto my Jenkins server and click manage jenkins-system information under the "Environment Variables" section the PATH variable is wrong. How can I change it? Jenkins is running as root but root's PATH is correct but Jenkins isn't pulling that correctly. Right now Jenkins can't find hg(mercurial) or anything else.

  • Scan all domain workstations for specific registry key/environmental variable

    - by Trevor
    I'm looking for scripts or software that can scan workstations on a domain for a particular environmental variable (for interest, it was used to store the SOE build version) and generate a report. Accuracy is key, I don't want any workstations skipped or missed. And considering workstations will need to be powered on for anything to remotely read from the registry (and there's no guarantee they will be), that means something that can sit and run continuously for a while, updating its own records as it goes. Does anyone know of such a beast?

  • OSX Server - How to set environment variable on network user login

    - by tmkly3
    I have a group of users on my server, "Developers", and I would like an environment variable to be set for them whenever they login. More specifically, when anyone in this group logs in, I would like the equivalent of: setenv ANDROID_SDK_HOME /Developers/Android/User to be set at login. I can do this with a login script if necessary, but what I'm asking is: is it possible to set this type of thing in Profile Manager, Workgroup Manager, Directory Utility, etc? Thanks - I've looked everywhere but can't find anything.

  • Python Instance Variable as Default Parameter

    - by DuneBug
    Hello, I have am writing a Python function that takes a timeout value as a parameter. Normally, the user will always use the same timeout value, but on occasion he may want to wait slightly longer. The timeout value is stored as a class instance variable. I want to use the class' timeout instance variable as the default parameter. Currently, I am implementing this as follows: def _writeAndWait (self, string, timeout = -1): if (timeout == -1): timeout = self._timeout I was just wondering, is the proper way to use an instance variable as a default parameter? Or is there a better way that would avoid the "if" check? Thanks, Ryan
