代码可读性例子

using namespace log4cplus;using namespace log4cplus::helpers;int main(){Logger _logger = Logger::getInstance("test");{SharedObejctPtr _append(new ConsoleAppender());{std::auto_ptr _layout(new PatternLayout("%d{} - %m[]"));_append->setLayout(_layout);}_append->setName("append for test");_logger.addAppender(_appender);}_logger.setLogLevel(ALL_LOG_LEVEL);LOG4CPLUS_DEBUG(_logger, "This is ...");return 0;}

用作用域来提高代码的可读性。
