"WebThe full quote is: I'd advise avoiding std::endl in general. Along with writing a new-line to the stream, it flushes the stream. You want the new-line, but almost never want to flush the stream, so it's generally better to just write a \n. On the rare occasion that you actually want the flush, do it explicitly: std::cout << '\n' << std::flush;. " - Cout.sync_with_stdio false
