Converting QString to std::string

Question:

You have a QString object and want to output its contents to the console using std::cout. However, the code doesn't compile due to type mismatch. How can you convert a QString to a std::string for output?

Answer:

To convert a QString to a std::string, use the toStdString() member function:

<code class="cpp">QString qs;
// do things
std::cout << qs.toStdString() << std::endl;</code>

This function internally uses QString::toUtf8() to create the std::string, ensuring Unicode safety. Refer to the Qt documentation for more information on QString: https: //doc.qt.io/qt-5/qstring.html
