Fewer lines of code would not necessarily be more efficient. Please read How to Ask and post an minimal reproducible example. Actually, you might want to consider posting to CodeReview, since you don't have a bug to track down. — jwdonahue just now
Q: How can I clean up the code for making a 10x10 times table using two dimensional arrays

NOKLOCPLUSI have been on the C++ learning grind for the last 2 weeks using caveofprogramming videos so don't judge too hard if this seems like a dumb question. My last lesson covered arrays and the assignment was to make a 10x10 times table using multidimensional arrays. I succeeded in making this times ta...

You can post this question on Code Review, including your current code, and ask for peer help to optimize it. Be sure to read that site's help center pages before posting, so that you make sure you do so properly. You can't ask this sort of question on this site, however - you have working code that you're asking for help optimizing. — Ken White 54 secs ago

Q: Correct usage of atomic structs and correct benchmarking

lukropI am wondering whether I correctly made the struct atomic, since in this benchmark showed quite a big difference, which is exactly what i need. Is there anything i could improve in terms of runtime? setting the members without the setter did not seem to make too big of a difference. #include <ios...

Q: Is this a reasonable way to test/compare javascript loop speeds?

you should ask this question in codereview, not here — Łukasz Kwieciński 33 secs ago
3:48 PM
@ŁukaszKwieciński Absolutely not. "Does someone also know why the status doesnt work" indicates the code does not work the way it should yet, thus it's not ready for review. Please familiarize yourself with Code Review's scope before making such recommendations. — Mast 38 secs ago
In general: your code does not work as intended or does not work at all -> SO; your code works, but you would like suggestions to optimize/improve it -> Code Review SE. If anything is not clear, feel free to ask about your question (providing a link) on [Meta SO](meta.stackoverflow.com). — Marco Bonelli 46 secs ago
@ŁukaszKwieciński The question is not an acceptable question for Code Review. — Peilonrayz 16 secs ago
@ŁukaszKwieciński Irrelevant. The code not producing the correct output is not a side-issue, it's one of the main reasons NOT to post on Code Review. We simply don't accept questions of which the code doesn't work yet. Whether it's on-topic on Stack Overflow is not our concern. You invoked the name of CR and it's bad form to redirect crap. Just close it, don't mention other sites. — Mast 59 secs ago
@Mast yeah, you're right, upon closer inspection this would need improvement before being possibly posted on Code Review SE. Also, this is a very common question that has probably been asked and answered a thousand times before. — Marco Bonelli 38 secs ago
Q: want to avoid return by value
