int port = ConfigManager::ReadInt("PORT_NUMBER", 8080);
int timeout = ConfigManager::ReadInt("TIMEOUT", 60);In this example, the ReadInt function retrieves the value of the key "TIMEOUT" from the configuration file. If the key is not found, it returns the default value of 60. The retrieved value is assigned to the variable 'timeout'. The ConfigManager library is a custom library with no package name associated with it.
