pseyfertTIL C++26 introduces _ as "I'm not going to use it, don't bother me with naming conflicts" (name-independent declaration) For things like auto [_, X, _, _] = some_fun();I know it from <a href="https://chaos.social/tags/rustlang" class="mention hashtag" rel="nofollow noopener" target="_blank">#rustlang</a> but wouldn't have expected it in <a href="https://chaos.social/tags/cpp" class="mention hashtag" rel="nofollow noopener" target="_blank">#cpp</a> .(Yes, I just browsed over the recent cppweekly episodes)

Koen Hufkens, PhDSo, I'm coming from Fortran mostly, moving to C++, and I've this explicitly vectorized Fortran code which runs column wise operations, e.g.: a = input(:, 1) + input(:, 2)Now, I'm wondering how to implement this the fastest using Rcpp/C++.I can use (Rcpp)Armadillo to implement the implicit logic, or loop through vector elements. Since the overhead of flipping between the two is quite some work I would love someone's take up front.<a href="https://mastodon.social/@eddelbuettel" class="u-url mention" rel="nofollow noopener" target="_blank">@eddelbuettel</a> <a href="https://mastodon.social/@eliocamp" class="u-url mention" rel="nofollow noopener" target="_blank">@eliocamp</a> ?<a href="https://mastodon.social/tags/rstats" class="mention hashtag" rel="nofollow noopener" target="_blank">#rstats</a> <a href="https://mastodon.social/tags/devops" class="mention hashtag" rel="nofollow noopener" target="_blank">#devops</a> <a href="https://mastodon.social/tags/Cpp" class="mention hashtag" rel="nofollow noopener" target="_blank">#Cpp</a>

INCD021Started my journey into C++ yesterday, and I'm so lost it's funny.. 😆 I can't remember when I felt so lost learning. I couldn't even get the my first class right without having to google way to much. But I did get an understanding of the const keyword on parameters and on member functions. So that's good.But a lot has happened with c++ since around 2000-2002, when I switched to C#.<a href="https://mastodon.gamedev.place/tags/cpp" class="mention hashtag" rel="nofollow noopener" target="_blank">#cpp</a> <a href="https://mastodon.gamedev.place/tags/relearning" class="mention hashtag" rel="nofollow noopener" target="_blank">#relearning</a> #
