According to various sources, '\n' gets translated to the current platform's line separator as long as the C++ file stream is opened in text mode. See, for example, <a href="https://stackoverflow.com/a/213977" id="LPlnk">https://stackoverflow.com/a/213977</a>.</div>

So <code>std::endl</code> would indeed likely be slower AND unnecessary to achieve platform independence.</div>

Many C++ books contain example code like this... std::cout << "Test line" << std::endl; ...so I've always done that too. But I've seen a lot of code from working developers like this</div>
