Udemy looked down on?
I'm a self taught C++ programmer, I am currently in a tester role which allows me to also learn and code in C++, working on embedded firmware and my own projects.
I did also take a course on Udemy on C++ (as well as UML and Multi-treading)
Is that looked down on by companies or uni-taught programmers?
I've got a job interview coming up and I wanna know how much weight a Udemy course actually carries.

Should I make a game
I am currently learning c++ atm and was thinking about projects to make, this would not be my first project I will tackle but one I will slowly build on for a while with my friends. Do you guys reckon it would be a good idea to potentially make a game in entirely in c++, my aim here would not to make the best game but make a game which would show my programming skills, my aim isn’t to break into game dev it just sounds like a fun but hard project?

A FOSS heuristic for the Set Covering
Hi everyone, I'm working on a C++ library implementing a heuristic algorithm for the Set Covering Problem: github.com/c4v4/cft
The SCP is a classic combinatorial optimization problem that asks, given a set and a collection of subsets, to find the minimum-cost group of subsets that covers everything in the original set. You can find SCPs in crew scheduling or test selection, for example.
Currently, commercial MILP solvers like Cplex or Gurobi are often the go-to option for SCPs. But, while they are powerful, well-designed heuristics can often achieve even better results (especially when the available time is tight).
Our implementation is based on the work of Caprara, Fischetti, and Toth. It was originally developed for a research project, but we've decided to clean it up and make it publicly available as a free, high-performing alternative.
We also hope the library serves as a helpful companion to the original paper, which can get a bit technical at times.
Since this is our first real open-source contribution, any constructive feedback is welcomed. We hope this library will prove helpful.
Thanks!

Dataflow analysis: any off-the-shelf tool recommendation?
Frequently, I find myself asking: can I get a complete list of every place in my code that will read this data item that I am about to produce?
Or, when I'm reading a data value, can I get a complete list of every code path through which I am receiving this value? I want to know if a given invariant is always satisfied.
Are there tools that automate some of this work?

Could you please recommend some courses on C++ distributed server?
Hello everyone, I am now taking a master project, and my major is computational mechanics, I have finished a 115 hours C++ 20 course on Udemy and have read through C++ primer, but now I don't know how to proceed, I want to do some jobs related to server development, especially for high performance game server, I think it is necessary to learn distributed server, but I don't know where to find related courses, could you please recommend some? either free paid version is fine, and I would appreciate it if you could recommend a roadmap for this project, thank you very much

Qbs 2.3 released
https://qbs.io/blog/release-2.3.0/
The post is a bit late, but nevertheless I'd like to advertise the new version.
Qbs is a build system originated at Qt and now is developed by the community as a general-purpose build system (mainly for c++, but we also have some support for other languages like java).
In this release we mainly focused on the better integration with IDE's (QtCreator fully supports new features, VSCode doesn't use them for now). We also did improvements to the mechanism responsible for locating external libraries, as well as general bugfixes

A comparison of the performance of C++ versions 14, 17, and 20. Performance was measured using Visual Studios unit test project and test explorer. 11 tests are run. 4 of them are exact tests, 1 of them, the longest running, is exact and multithreaded. The rest have some randomization
Here are the results, you be the judge of which version of C++ performs better.

Is MacBook good for C++ developer?
Hi. I am a C++ developer, and I write code for both Linux and Windows, depending on the project. Currently, in my country (I'm from Ukraine), there are frequent power outages (3 hours with power, 4 hours without, and so on), and I am looking for a laptop with a long-lasting battery. Since MacBooks have excellent battery life, I am considering buying one, but I have a few questions.
Will I experience a significant loss in performance when building a C++ project in Docker using an x64 Ubuntu image and the Rosetta emulator?
Will there be a noticeable drop in performance if I use x64 Windows through an emulator?
Is it worth making these sacrifices, or should I buy a Windows laptop with a less impressive battery?
I have a powerful PC that I’m using for work, and I can use It for building projects, but when the power is on.

C++: freeing resources in destructors using helper functions
https://pvs-studio.com/en/blog/posts/cpp/1125/
https://redd.it/1cysfbi
@r_cpp
Why in one case, copy Ctor is called, while in another case, another Ctor is called?
This is the common code snippet for two cases:
#include <string>
class A {
public:
//string Ctor
A(const std::string& s = std::string()) : ps(new std::string(s)) { }
//Copy Ctor
A(const A& p) : ps(new std::string(p.ps)), i(p.i) { }
~A() { delete ps; }
private:
std::string ps;
int i;
};
Below is case 1:A v = "abc";
I was told by someone that the compiler would do the following steps:
1) Implicitly convert "abc" to a temporary std::string object.
2) Implicitly convert the temporary std::string object to a temporary A object.
3) Call the copy Ctor with the temporary A object to construct v.
Because there are two implicitly conversions before the copy Ctor function, the compiler reports an error (cannot convert from 'const char [4\]' to 'A').
Below is case 2:A v = std::string("abc");
From the step by step debugging, I can figure out that the compiler would do the following steps:
1) Explicitly convert "abc" to a temporary std::string object.
2) Call the string Ctor with the temporary std::string object to construct v.
My question is as follows: After step 1) of both cases, we got a temporary std::string object. I cannot see any differences at this point between two cases. But after that, two cases run in different execution paths as detailed in above steps. Why the difference after the same temporary std::string object is obtained? Thanks.

Run 2 sounds at the same time in Console C++ with Windows.h
Hello everyone, currently I am having difficulty running 2 sounds at the same time, PlaySound(TEXT("Sound//soundtrack.wav"), NULL, SND_FILENAME | SND_ASYNC | SND_LOOP); PlaySound(TEXT("Sound//click.wav"), NULL, SND_ASYNC);
When one is turned on, the other is turned off. But I want the background music and sound effects to run in parallel. Because this is a project that is required to be done by Console C++ and cannot install external libraries, it is having difficulty. I don't know if there is any way, please help. Thanks a lot !!!

Is there a website with multiple choice questions that cover special cases for practice?
I'm currently taking a summer course on C++ and was wondering if you guys know about a website where I can find multiple choice examples. Every week I have quizzes and I only have a less than 10 minutes to answer all the questions, and they sometimes cover very specific cases that would be impossible to guess unless I had written the exact same code and run it. I would prefer if they covered these types of questions so that I can practice more. Thanks
