FWIW, Google&#39;s C++ style guide explicitly requires passing pointers to arguments (whenever possible) when they are to be modified or used as out parameters, and passed by const&amp; when they are not. This makes it more obvious at the caller&#39;s end which parameters are going to be modified and which ones aren&#39;t.<div>
