i new programming. moving on c++ c in college courses, , encountered haven't seen before in c. after type, either in function declaration or passing parameter, & follows type. example, use struct called customer in 1 of our projects, , of functions pass customer& . why ampersand after type, opposed in front? thanks! references in c++ allow cleaner way execute following code: int x = 16; int* y = &x; cout << *y; which written instead as int x = 16; int& y = x; cout << y; when defining functions, reference allows function change value of parameters without causing user of function put ampersand before everything. e.g. void func( int& ) { = 5; } void main() { int = 10; func( ); cout << a; // output '5' } be careful this, programmer using functions without checking implementation might not realize function changing value of parameters unless intent obvious. it's better use pointers or return s

how differentiate integer , double. example if wanted integer , verify it. if integer output "you correct" else "you entred wrong. try again". import javax.swing.*; public class inputexceptions { private static int inputint; private static double inputdouble; public static int inputint() { boolean inputok = false; while (inputok == false) { inputint = integer.parseint(joptionpane.showinputdialog("enter integer")); try { inputok = true; } catch (exception e) { joptionpane.showmessagedialog(null,"*** error: value entered not integer ***"); } } return inputint; } public static void main(string[] args) { joptionpane.showmessagedialog(null,"*** integer correct input: " + inputint() + " ***"); } }

i have 2 two tables related third relationship table. basically, have many fits, can use number of tags, , i'm trying query fits tagged tag using tagid. tag.py: tags_table = table("tags", saveddata_meta, column("tagid", integer, primary_key = true), column("name", string, nullable = false, unique=true)) mapper(tag, tags_table) fit.py (stripped down) fits_table = table("fits", saveddata_meta, column("id", integer, primary_key = true), column("ownerid", foreignkey("users.id"), nullable = true, index = true), column("name", string, nullable = false), column("timestamp", integer, nullable = false)) fit_tags = table("fit_tags", saveddata_meta, column("fitid", integer, foreignkey("

so passed file filewriter , passed printwriter. however, upon assignments instructions im supposed print these variables pass printwriter using tostring method in superclass. assignment thats why rules clear how instructors wants output be. system.out.print("please enter file name: "); filename = input.next(); file fw = new file(filename + ".txt"); accountwithexception acctexception = new accountwithexception(fullname, balance, id, rate); system.out.println(acctexception.tostring()); <---this works // pass object printwriter , pw write file pw = new printwriter(fw); // print created file pw.println(firstname); pw.println(lastname); pw.println(balance); pw.println(id); pw.println(rate); system.out.println(pw.tostring()); <---doesn't work. prints location , im supposed somehow use overloaded tostring method output data within file (i guess after written) yo

okay, posted same question earlier , got on arrays/vectors , on. fixed people told me run issues program gives me bunch of errors. , time, don't see wrong. makes perfect sense me doesn't computer , i'm mere novice. so here's i'm trying accomplish. reading names file called names.dat , has names saved this: collins, bill\n smith, bart\n allen, jim\n . . . holland, beth i'm trying sort these names alphabetically (both ascending , descending order). let alone descending order now, wrote program supposed sort these names in ascending order. keeps spitting out errors don't understand meanings of. don't know if errors coming deque , string i'm trying define, or other parts. here's got far. #include<iostream> #include<fstream> #include<iomanip> #include<deque> using namespace std; const int size = 20; void setascendingsort(string [], int); void displayarray(string [], int); int main() { deque<string> name

i'm using node.js create irc bot asks trivia questions. far works great, wanted implement system generates hints providing underscores each letter. time passes, fills in blanks. if nobody gets answer before blanks filled in, bot moves on. (if not in single-question mode) the issue: if nobody answers question, bot moves on next 1 intended. bot supplies two hints @ same time. repeats first hint, other times it's satisfying else statement , providing next hint. i have troubleshooted verify function gethint being called once. i've been staring @ code 2.5 hours , i'm beginning lose hope. i'm brand new javascript, first time coding in it. appreciated. example 1: satisfies if (there no hint) twice bot> drummer beatles? bot> _ _ _ _ _ _ _ _ _ _ bot> r _ _ g o s _ _ r bot> r _ n g o s t r r bot> oh man, nobody got answer! was: ringo starr bot> president of united states? bot> _ _ _ _ _ _ _ _

i have scenario, javascript client connects rest sever expose jsonp api's on domain. my question if server stateless, if server has /session api generate session key, meaningful other succeeding requests? that is, how can server side session on domain usable in pure front-end scenario. in typical web app, front-end loaded same domain thus, when app loads , authenticates, session objects may generated. yet kind of situation client (is pure frontend) lives somewhere else in internet , not in same domain of rest server. session not applicable correct?

presently built automation framework uses selenium webdriver+ specflow + nunit, , suing bamboo our ci run our job against our every build. we written build.xml handle our targets (like clean, init, install latest build, run selenium scripts, uninstall build. etc) ant command read tag name build.xml , runs respective feature/scenarios based on tags (like @smoke, @regression)with nunit in ci machine. now our requirement use selenium grid divide scripts different machine , execute above set-up. grid has divide scripts based on feature file or based on tags.how achieve this. is there thing need done under [beforefeature] , [beforescenario] ? if provide in details steps or link explains detail steps great help. please 1 can in regards. thanks, ashok you have misunderstood role grid plays in distributed parallel testing. not "divide scripts", provides single hub resource through multiple tests can open concurrent sessions. it role of test runner (in cas

i've created criteria retrieve list of items. although expected, no result returned if condition not work. criteria cre = session.createcriteria(name.class,"name); cre.add(restrictions.eq("name.fname","alex"); list<name> names = (list<name>) cre.list(); i used both following 'if' conditions neither works 1) if(names.isempty()) system.err.println("cre empty"); 2) if(names != null) system.err.println("cre empty"); you can use size() of list. if list's size 0, empty. if(names.size() == 0){ //it empty } if(names.size() > 0){ //it **not** empty }
