Printing float with precision 2 but without decimal(.) in C++ -

-

please consider code snippet shown below:

// setprecision example #include <iostream>     // std::cout, std::fixed #include <iomanip>      // std::setprecision  int main () {   double f =3.14159;   std::cout.precision(2);    std::cout << f*100 << '\n';   return 0; }

what want print on screen 314 (i.e. print f without decimal precision 2)

i want thinking of first setting precision 2 , multiplying 100.

but seems precision applied on f*100. can suggest of way apply precision on f multiply number 100 , print precision 0?

multiply 100 , print precision 0.

int main () {   double f =3.14159;   std::cout.precision(0);    std::cout << std::fixed << f*100 << '\n';   return 0; }

i'm trying write c++ client talk websocket server written using nodejs , socket.io. can't c++ client establish websocket connection; server drops connection right after client requests http connection upgraded websocket. i used tcpdump watch packets going , forth. when use websocket server browser, works great , tcpdump output shows packets going , forth. when try connect server using c++ client, websocket connection never gets established. output tcpdump shows upgrade request being sent server followed server dropping connection. i tried replicating sequence of events using nc . connected server (running on port 8080) , copy-pasted exact set of headers sent browser, captured tcpdump. duplicate of working headers, connection dropped. there no output on server end indicating why connection gets dropped. here headers sent: get /socket.io/?type=player&eio=3&transport=websocket&sid=7mdclht_8ctsd6f4aaac http/1.1 host: localhost:8080 connection: upgrade prag...

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
