Yes. That's orthogonal. And people have been using CMake with Qt (and moc) for almost as long as cmake exists

You should be fine with the LGPL license of Qt.

I find it ironic that you answer to a comment asking for links, but you don't provide any. (Same for the other comments in this thread)

I believe I understand correctly UB and unsafe. The cxx crate and the autocxx tool should make sure that the exposed C++ functions only take arguments types which have well defined semantics. In your example, a rust Box<T> maps to a r

The point is that the C++ code should be safe because the C++ programmer should not introduce UB on its C++ code. If the C++ code invoke UB, that is a bug in the C++ code which should be found by reviewing the C++ code alone. No need to wri

Imagine what proponents to heliocentrism such as Galileo had to face explaining their theory and how it explain a simplified elliptic orbit for the planets rather than the strange curly orbits known by geocentrists. They'd be confronte

I did not see digraphs mentioned. Could look like <: and :>. The formatting tool could even normalize that to some prettier unicode.

I believe you got it backwards. The price of bitcoin determines how much the miners are going to spend to produce it. (Or we are both wrong)

Could also try to use the smallvec crate in this case, which put small allocation on the stack https://docs.rs/smallvec/

But with rust you have to re-learn the language every six weeks as it changes so fast. (/s)

No, it hasn't. Actually C++20 comes with only the minimal support for coroutines in the std library. If you want to do anything useful, you need to implement a promise type yourself which is very hard to do without using one library th

I don't know about the others, but C++ don't have a default implementation as part of the standard. If you want an event loop, you need to use one of the many libraries that provide one.

I have a laptop I bought in 2009. I installed archlinux when I got it and upgraded regularly, and it still works.

Romans needed many more than 3 "digit" (or rather letter) to represent this date. Also, the AD system (counting the year since the birth of Jesus Christ) was introduced much later.

Personally, I stick with K&R C. I haven't gotten around to update all my with function signatures. whats is the thing with putting (void) all over or specifying the return type of my functions? Really, these explicit function decla

On the other hand, you could argue that the r# gives you "more prominence" which is exactly the stated goal of using that macro.

In C++ you can't hide a variable with another of the same name in the same scope. So you'd want to give different names to all the 'state' variables.

That's assuming players knows about the other players, which is not specified in the problem description. It is not even specified if the same game is played several time with the same rules. Given the description from the article: &gt

If the host knows where the car is, why would it ask the player to change door if he knows the player already choose a goat? The problem should specify that those are the rules of the game that the host always open a door. Otherwise, as a h
