Paul<p>I have seen this advice on struct padding in C a few times - especially ordering fields from largest to smallest.</p><p>Is there any reason why the compiler doesn't do this for you? Presumably it knows the size at compile time, because sizeof can be applied to both the fields and the struct?</p><p>Or is the compiler avoiding this because you might be assuming a certain memory layout?</p><p><a href="https://tomscheers.github.io/2025/07/29/writing-memory-efficient-structs-post.html" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">tomscheers.github.io/2025/07/2</span><span class="invisible">9/writing-memory-efficient-structs-post.html</span></a></p><p><a href="https://social.xk7.net/tags/c" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>c</span></a> <a href="https://social.xk7.net/tags/optimisation" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>optimisation</span></a></p>

Today I've finished #teaching to my current customer how to maintain the #software I've developed for them once I've left. Two sessions of 3h and 3h40, teaching to 4 people, all in #japanese of course. A bit tired tonight, but both the users and the IT team are super happy with what I've done (solving a #combinatorial #optimisation problem to save them several hours of work every week and help #organic #farmers ) and I was happy to teach about what I love the most: #programming .
Bonus point for preaching about #testdrivendevelopment and the beauty of #cprogramming .

Also still looking for my next contract ! #fedihire #jobsearch
