i using following lambda , getting error. can't figure out why compiler doesn't doing. std::string captchaword(6, 0); std::generate(captchaword.begin(), captchaword.end(), []() { unsigned int num = randomizer('z' - 'a' + 1 + '9' - '0' + 1); char ch = num + 'a'; if (num >= 'z' - 'a' + 1) { ch += '0' - 'z' - 1; } return ch; }); by way, randomizer function following signature: unsigned int randomizer(unsigned int); this error message get: error c3499: lambda has been specified have void return type cannot return value. you have specify return type: []() -> char { // code; } the automatic deduction works if whole lambda consists of single return statement only (in c++11), otherwise, need specify type. see documentation on lambda on cppreference . in c++14, rules allow other statements before return.

i have 3 date values in table, namely activationdate, registrationdate, , creationdate , have select show name of column least value. i used select least(activationdate, registrationdate, creationdate) table name and returns smallest value. however, want know of these 3 smallest value. so, expected outcome name of column has least date can activation date, registration date or creation date. for solution, kindly state result if 3 of them have similar values? return or one? thanks you need test least value against each column, in conditional statement. assuming following table structure create table `test` ( `activationdate` datetime default null, `registrationdate` datetime default null, `creationdate` datetime default null ) with these values mysql> select * test; +---------------------+---------------------+---------------------+ | activationdate | registrationdate | creationdate | +---------------------+--------------------

i want have class can accept assignment both , int , string literal. string literal, turns out, must of type char[]. have whole lot of data types taken assignment operator. compiler gets confused between these two. how interchangeable char can int, use quick ascii comparisons. i'd know if there's way compiler stop trying send string literals int version of overloaded operator. none of other types have problem, these 2 getting mixed up. mydatatype& operator = (int right); mydatatype& operator = (const char &right); when try: mydatatype test; test = "hello world."; the compiler tries interpret string literal int , throws error: error: invalid conversion ‘const char*’ ‘int’ [-fpermissive] thanks. if string must of type char[] , must have [] , or * , in signature. mydatatype& operator = (int right); mydatatype& operator = (const char *right); or mydatatype& operator = (int right); template<size_t n>

i building chat app pubnub. problem app/frontend point of view, how should time (server time). if every message sent server, server time there. 3rd party service pubnub, how can manage this? since app sends messages pubnub rather server. dont want rely on local time users might have inaccurate clocks. the simplest solution thought of is: when app starts up, server time. record difference between local time , server time ( diff = date.now() - servertime ). when sending messages, time date.now() - diff . correct far? i guess solution assumes 0 transmission (or latency) time? there more correct or recommended way implement this? your use case reason why pubnub.time() exists. in fact, have code example describing drift calculation. https://github.com/pubnub/javascript/blob/1fa0b48227625f92de9460338c222152c853abda/examples/time-drift-detla-detection/drift-delta-detection.html // drift functions function now(){ return+new date } function clock_drift(cb) { clock_dr

i add libraries slimcontroller , swift mailer in slim project, when in route goes well: route::get('/send', function() use ($app, $mailer) { $message = swift_message::newinstance('activation code') ->setfrom(array('xxx@gmail.com' => 'xxx')) ->setto(array('xxxs@gmail.com' => 'xxxs')) ->setbody('test'); // send message $results = $mailer->send($message); // print results, 1 = message sent! print($results); }); but after run on controller there error class mycontroller extends \slimcontroller\slimcontroller { public function getregisters() { $data = (empty(\session::flash())) ? array( 'token' => \token::gettoken() ) : array_merge(\session::flash(), array( 'token' => \token::gettoken() )); return $this->render('auth/register.html', $data); } public

the purpose of method iterate through 2d array of integers called grid[][], , translate integers based on maximum , minimum values smaller range between 100 , 250 (the original minimum value becomes 100, original maximum value becomes 250, , in between calculated respectively). when method called, division 0 arithmeticexception occurs. clearly i'm making logic mistakes here... don't see fix. can help? public int greenvalues(int arrayval) { int max = 0; int min = 0; int colorvalue = 0; int temp; (int = 0; < grid.length; i++) { // finds maximum , minimum numbers in file (int j = 0; j < grid.length; j++) { if (max < grid[i][j]) { max = grid[i][j]; } if (min > grid[i][j]) { min = grid[i][j]; } } } int arrayrange = (max-min); // arrayval, arrayrange, , max , min 0 temp = (((arrayval-min) * color_range) / arrayrange)

i have following sql query: select s.name, count(sc.id) classes students s left join studentsclasses sc on s.id = sc.studentid group s.name having count(sc.id) = 0 order count(sc.id); that query gets count of students classes , returns students least classes. how can convert c#? attempt not yield expected result. have: var query = (from students in ent.students join classes in ent.studentsclasses on students.id equals classes.studentid gj subpet in gj.defaultifempty() select new { students.name }).tolist(); however returns names of students registered in courses. ================================ here tables: ================== studentsclasses ---------------- id (registration id of class) studentid (id of student taking class) classid (id of class) ---------------- ================== students --------------- id (id of student) name (name of student) gradelevelid (grade of student) -----
