how to use std::getline(std::cin, s);

[Natural_Bugger]

I'm trying to build some console application using "example" code.

i have been looking online and it looks correct.
http://www.cplusplus.com/reference/string/string/getline/

but it does not work or compile in Qt creator:

QString s;
std::getline(std::cin, s);

error:

main.cpp:34: error: no matching function for call to ‘getline(std::istream&, QString&)’
   34 |     std::getline(std::cin, s);
      |                             ^

how to solve?

regards.

By reading the documentation of std::getline(): 'Defined in header <string>'

std::getline() knows about std::string but it doesn't know about QString. So, store your input in a std::string first and then call QString::fromStdString().

See https://doc.qt.io/qt-5/qstring.html#fromStdString
