Using Macbook Pro for C++ Development What is the right way to develop C++ projects on macos which are intended to run on Mac & Linux Servers and shared across other developers all working remotely. So other dev might have linux platforms wont need complicated setups. Projects uses arrow, aws, pcap, gsl, blas etc. I have tried around using a combination of brew, docker, pixi, cmake, Clion and VsCode. But I havent been able to narrow down to a truly shared and portable repo setup where two users on two different working setups can work seamlessly. Wondering what have people used and found pros&cons of their approaches. https://redd.it/1p454td @r_cpp

Como debería comenzar ? Hace tiempo me lo he venido planteando desde muy pequeño me ha atraído todo lo relacionado con la computación y descubrí el mundo del código al principio fue un golpe porque ... Osea no sabía un comino de inglés y no entendía nada de nada , pero quiero aprender y quisiera saber cómo empiezo , mis recursos son escasos para no decir que nulos , tengo laptop móvil pero no dispongo de nada para un curso ni nada , quisiera saber si hubo alguien en mi posición y pudo aprender y quisiera saber cómo lo hizo https://redd.it/1p3zd2k @r_cpp

C++ game using library or game engine? C++ game using library or engine? I am a beginner so please bear with me. I want to make a 2d top view game for my uni project and at least 70% c++ is requirement. I am trying/using sfml for now(am currently following tutorials instead of jumping in right now). But am confused that is sfml the best option for this? I think game engine would be easier for what I want and level designing would be much easier with an engine. I want some advice as should I continue with sfml or cocos2d or godot with c++ would be easier? As c++ is a requirement so can't use unity and have heard that unreal is not a good option for simple 2d? https://redd.it/1p3venm @r_cpp

What is the most modern way to implement traits/multiple dispatch/multiple inheritance? I am coming back to C++ after a few years of abstinence, and have since picked up on traits and multiple dispatch from Rust and Julia, and was hoping that there is an easy way to get the same in C++ as well. Usually i have just written a single virtual parent class, and then i had a container of pointers onto children. This was ok for smaller use cases and did polymorphism fine, but it would fail if i would like to implement more interfaces/traits for my objects. I.e. i want to have shapes, several are movable, several others are also scalable, not all scalables are also movable. What should i look into? I am pretty confused, since C++ does C++ things again, and there does not seem to be a single unified standard. There seems to be multiple inheritance, which i think would work, but i learned i should never ever ever do this, because of diamond inheritance. Then there seem to be concepts, and type erasure. This seems to have a lot of boiler plate code (that i don't totally understand atm). There also seems to be some difference between compile time polymorphism and run time polymorphism. I do not want to have to suddenly refactor something, just because i decide i need a vector of pointers for a trait/concept that previously was defined only in templates. What would you use, what should i learn, what is the most future proof? Or is this a case of, you think you want this, but you don't really? https://redd.it/1p353bp @r_cpp

Thinking of moving to C++ So to make a super long story short, I graduated a couple years ago with a bachelors in software development. Learned and starting doing more with C#, shortly after that I had a job offer. But I needed to have lung surgery and would need a lot of time off and the offer was withdrawn (hindsight I should have not said anything until after I started lol ) and had a long recovery and health issues. Im back to 100% and havent done much coding or anything in that gap of time while I was sick. Id like to get back in to it but deciding between going back in to C# or pivoting and learning C++. C++ I think is more prevalent in career fields Id enjoy, aerospace, embedded, games (though realistically probably not where id actually go), and some government work. I also know C# can be used in those fields as well, but I did really enjoy the few C++ courses I had back in school and its intrigued me ever since. So really im stuck deciding if I do C# and then try to move to a C++ role after some experience, or just go for C++ off the rip. I know entry level is gonna be difficult for both but feel like itd be even more so for C++. Im also in Missouri and not sure how prevalent C++ even is here, though im also not opposed to moving ha. https://redd.it/1p2g2ca @r_cpp

Simple MPSCQueue with explanation My previous post got deleted because It seems like AI detector has disliked the "polished" style of the post. I guess it should be rewritten in a more "casual" way, with grammar errors. Sorry for duplication if anyone has seen this already. \---- During my free time, I have stumbled upon such segment of C++ as "low latency" and "lock free". This topic has initially fascinated me so much, because I couldn't have even imagined that some thing like this could even exist, and is actively used in a very interesting and specific segment of the market... But that is a story for another time :) I have decided to get familiar with the topic, and as my first step, I wanted to implement something. I have chosen MPSC (Multiple Producer, Single Consumer) queue, but I've quickly realised that the entry barrier is overly high. I literally had no understanding of where I could start. I spent several weeks gathering knowledge bit by bit, studying advanced multithreading, atomics, memory ordering, and lock-free algorithms. Finally I came up with something I want to share here. I thought it would be valuable to create a detailed walkthrough, which can be used either by me in future, when I get back to this in maybe several month or years, my friends who would love to learn about this topic, or anyone else who would find themselves in a situation like this. This project is for sure not the best, not ideal, and not something universe-changing. It is just a "school-grader-level" project with the explanation, hopefully understandable to the same "school-grader". I, personally, would have loved to have an article like this while I was learning, since it could save at least several weeks, so I hope it helps others in the same way. https://github.com/bowtoyourlord/MPSCQueue Any critics welcome. https://redd.it/1p2bizu @r_cpp
