QUrl url("https://www.example.com/search?q=apple"); if (url.hasQuery()) { qDebug() << "This URL has a query string!"; } else { qDebug() << "This URL does not have a query string."; }
QUrl url("https://www.example.com/about"); if (url.hasQuery()) { qDebug() << "This URL has a query string!"; } else { qDebug() << "This URL does not have a query string."; }This code creates a QUrl object representing the URL "https://www.example.com/about", and checks if it has a query string. Since this URL does not have a query string, the output of this code will be "This URL does not have a query string.". Based on the use of the QUrl class and its functions, it can be determined that it is part of the Qt framework's QtCore package/library.
