i doing tests code did not compile, , discovered code: struct { a(int) {}; virtual void foo() = 0; }; struct b : public virtual { virtual void bar() = 0; }; struct c : public b { c() : a(1) {} virtual void foo() override {} virtual void bar() override {} }; int main() { c c; return 0; } in c++11 fails compile (on g++ 7.0.1) ‘b::b()’ implicitly deleted because default definition ill-formed , while in c++14 compiles successfully. i've tried find out new feature of c++14 allowed work, no avail. description in cppreference not mention of sort seems. why can code compile in c++14 not in c++11? definitively it's bug in gcc 7 because when have checked out code in online compiler gcc 7+, has worked without kind of problem. so here give ide online can set favorite compiler , try tests, if want. https://godbolt.org/ sorry can't better couldn't reproduce error.

i trying watson conversation api on android phone. had made model on watson , completed app. works fine when giving irrelevant inputs gives 1 of intent instead of giving negative response. had created separate conversation triggering on else. when try conversation on watson works perfect, out put json phone doesn't contains 'anything else' responses every flow, watson tries recognize intent, can see level confidence every input user in 1 payload window inside project ibm developers here . or can did debugging data return in app. one idea create 1 flow conditions confidence, entities, regex, context variable or true condition. true condition flow did watson talk user if 1 intent less confidence inside condition, or according flow, return want if use conditions entities or regex. simon did 1 example conditions entities , context variables , regex , check link: simon example . and can did conditions confidence level make sure if user type correctly intents

i using microsoft graph api log users webapp using domain email. i able read users basic profile using $token = $_session['access_token']; $graph = new graph(); $graph->setaccesstoken($token); $response = $graph->createrequest("get", "/me")->setreturntype(model\user::class)->execute(); var_dump($response); is there way can read groups? or way can instruct domain admin pass information app? you can using memberof method: https://graph.microsoft.com/v1.0/me/memberof . note you'll need 1 of following permission scopes added initial token request. directory.read.all directory.readwrite.all directory.accessasuser.all regardless of of these scopes choose, require administrative consent before regular user can authorize them. this, you'll first need have them go through “admin consent” workflow. workflow requires administrator once complete users of application have “admin consent” restricted scope. for example,
