i idea modify array in function need declare parameter reference in function definition: bool sortinput(ifstream &infile, studenttype (&students)[maxsize], int size) and declared prototype since wouldn't compile otherwise: bool sortinput(ifstream &, studenttype (&students)[maxsize], int); however doesn't seem pass array reference. make call different function , doesn't see of changes (all print array prints nothing). know fact array has been modified because printing within original function shows changes, don't seem carry on global array variable , stay within scope of function modifies despite being passed reference. i've read countless other threads , google searches i'm sure function definition proper state proper form prototype. you don't have pass array reference because passed pointer. pass size. in sort function copy of variable size modified in main function zero.

for example, suppose using atomic spinlock on integer flag ensure 1 thread modifies wait-queue mutex maintains @ given time. when thread tries lock mutex, want enqueue , set flag 0 before blocks , unlocker dequeue thread queue , set runnable. consider 2 threads present, 1 locking , other releasing mutex @ same time. if locker preempted after added himself queue , set flag 0 (but not blocked yet) , unlocker tried dequeue , make thread runnable, wouldn't useful since thread hasn't blocked yet. make-runnable call waste more importantly, locker thread block after , remain blocked forever. how atomicity achieved ensure correctness? similar scenario can imagined in condition variables release of mutex , blocking itself.

i'd define default folder name on home screen apps (which ad hoc distributed), such default apps when dragged ("productivity", "utilities", "games", "navigation"): instead of default name "folder": how can achieve this? edit: i tried adding lsapplicationcategorytype info.plist, doesn't seem affect anything. i think work on appstore versions. tested bunch of ad-hoc releases , appstore releases. - ad-hoc releases - "folder" name appears. appstore versions - app, moved onto other app - it's category name used. (in case ad-hoc moved onto appstore app, appstore app's category used). anyways, checked out lsapplicationcategorytype https://developer.apple.com/library/ios/documentation/general/reference/infoplistkeyreference/articles/launchserviceskeys.html#//apple_ref/doc/uid/tp40009250-sw8 did use example "education" - public.app-category.education ? either way - might not...

i have implemented service updates location in background, android app not working(crashed) while existing application using key. following code. public class locationservice extends service { private static final string tag = "location"; private locationmanager mlocationmanager = null; private static final int location_interval = 0; private static final float location_distance = 0f; private static context mcontext; private static int messagecount; private class locationlistener implements android.location.locationlistener{ location mlastlocation; public locationlistener(string provider) { mcontext = (context)locationdetails.locationcontext; log.e(tag, "locationlistener " + provider); mlastlocation = new location(provider); } @suppresswarnings("deprecation") @override public void onlocationchanged(location location) { try { messagecount++; log.e(tag, "onlocationchanged: ...

i want validate datagrid cell namely item column when user input against database table itemmaster .my doubt method best me validate input ,validationrule or idataerrorinfo ? this question 100% duplicate. have found answer yourself. use idataerrorinfo because able validate input inside viewmodel able access values/properties/data if needed validation. futhermore able swap viewmodels , change validation not able achieve validationrules easly. validation of viewmodel properties should done in viewmodel. centralized , testable. shouldnt not become part of view except has whatever reason. you should use validationrules when have binding between 2 control properties in scenario validation belongs "view" anyways , stays inside view part of mvvm.

how can "write" arraylist in file, can download after writing? 1 element in list 1 line in csv-file. for example: have arraylist<string> mylist = service.getlist want write in file. in simple client-only-application easy. have apache wicket . nice, have filebrowser, can specify, in directory want download it. i thought, work way: final file filetosave = new file("exported objects.csv"); writer writer = null; try { writer = new bufferedwriter(new filewriter(filetosave)); writer.write(""); (obj o : listo) { writer.append(o.getasd); } } catch (ioexception ex) { // report } { try { writer.close(); } catch (exception ex) { } } but won't. have use jboss-server . on local jetty-served worked, on jboss-server it's not possible way. wicket-version: 1.4.7 see wick...

i wrote simple fortran code in order following: assume have integer numbers n1 , n2 have common divisors. example 3 , 6 both divided 3. here code program test integer i,n1,n2 write(*,*)' please enter 2 numbers: ' read(*,*)n1,n2 i=2,10,1 if(mod(n1,i).eq.0.and.mod(n2,i).eq.0)then n1=n1/i n2=n2/i endif n1=n1 n2=n2 enddo write(*,*)n1,n2 pause end this works fine example (3,6). however, there cases (4,8) in numbers have more 1 common divisor, in case 2 , 4. example (16,24). want compute maximum common divisor of 2 numbers , reduce them (i.e. 3,6 1 , 2), code returns first 1 (4,8 returns 2, 4 instead of 1,2). how should modified in order calculate maximum divisor? many in advance! you stay i , till if -statement false . in other words: if number can divided i , don't go i+1 , try divide i again. edit: think easiest way use do while -loop. calculate divisor, have multiply i . gcd = 1 i=2,10,1 while (mod(n1,i).e...

i'm inexperienced java , nearing finish of first android app, when worst fear happened , reached error have don't know how interpret. the basics of app 5 lists, selected drawer menu. each list opens static xml views contents on it. works in portrait smoothly. in landscape, view dualpane, list on left, , contents on right. getting there works fine too. error when go landscape on 1 list, later on try going landscape on list. can please try me figure out happening? main activity import android.content.context; import android.content.intent; import android.content.sharedpreferences; import android.content.res.configuration; import android.net.uri; import android.os.bundle; import android.support.v4.app.actionbardrawertoggle; import android.support.v4.app.fragment; import android.support.v4.app.fragmentmanager; import android.support.v4.app.fragmenttransaction; import android.support.v4.view.gravitycompat; import android.support.v4.widget.drawerlayout; import android....
