Hey ,I am a student learning QT using C/C++.I started doing network examples few days back and wasn't able to understand the following snippet from an example.
Pls help me understand it.



Qt Code: 
  1. QNetworkConfigurationManager manager;
  2.     if (manager.capabilities() & QNetworkConfigurationManager::NetworkSessionRequired) {
  3.         // Get saved network configuration
  4.         QSettings settings(QSettings::UserScope, QLatin1String("Trolltech"));
  5.         settings.beginGroup(QLatin1String("QtNetwork"));
  6.         const QString id = settings.value(QLatin1String("DefaultNetworkConfiguration")).toString();
  7.         settings.endGroup();
  8.  
  9.         // If the saved network configuration is not currently discovered use the system default
  10.         QNetworkConfiguration config = manager.configurationFromIdentifier(id);
  11.         if ((config.state() & QNetworkConfiguration::Discovered) !=
  12.             QNetworkConfiguration::Discovered) {
  13.             config = manager.defaultConfiguration(); 
  14. }
