Chris, I thought this, too, until Ryan forced me to look into it further. Thanks, Ryan :) 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, https://stackoverflow.com/a/213977. So std::endl would indeed likely be slower AND unnecessary to achieve platform independence.
