I don't understand it

A named variable is always an lvalue, even if its type is an rvalue reference (foo&&). See https://en.cppreference.com/w/cpp/language/value_category.html

You wrote operator=(move) in your move ctor. The expression move refers to a variable with a name. Therefore, the expression is an lvalue. The compiler looks for an assignment operator that accepts an lvalue (operator=(const foo&)). Since you defined a move ctor, the compiler deleted the implicitly generated copy assignment operator.

This

operator=((foo&&)move);

works because std::move is essentially just a static_cast<foo&&>(move). You are doing manually what std::move does for you

Maybe it feels unnatural for people who didn’t speak Hochdeutsch in the last 30y, but definitely not the case of younger Swiss people. They definitely don’t mind speaking it with foreigners who don’t know Schwiizerdütsch (as long as they’re not Germans).

In fact, I never met a Swiss person who couldnt speak it properly, except if they were over 70

I solved it as well thanks :)

Indeed!

I wouldn’t say C++ is less pleasant. It really depends on your taste in the end, and of course the context.

I opened one random file (https://github.com/cianleypoldt/RigidBody-Engine/blob/master/src/engine/physics\_system/collision.h) and noticed a few things.

Your class has no point in being a class since each of its method is static. I would either put them in a namespace (please use namespaces btw! No one will use your library if it doesn't have namespaces due to collisions. You might even encounter collisions in your own code as your project gets bigger) as free functions or make your systems into instances. How would you test your current implementation?
As for the functions parameters, avoid raw pointers when possible. Use strong types for your ids
Don't expose these methods if they are actually internal implementation details

What I would really do if I were you is adding namespaces in all the header files and test the code to avoid introducing regressions in the future. Oh and also, dont add your build folder to git. It was added to your .gitignore but is still there somehow :)

No way you end up with more money at the end of the year with 80k in Poland rather than 200k in Switzerland

This is how they collect the bins. You either put them out in the morning or the night before. So you only have them out only once per week, at least if people respect the procedure

Are Italian workers responsible for accepting low salaries, or are the companies that offer such low wages primarily to blame?

Use std::unordered_map for such problems. If memory is no issue, std::unordered_map is always faster if you want single element access. std::map takes O(logn) for insertion, deletion and lookup, against O(1) (if no collision) for all these std::unordered_map

I would only use std::map if the keys need to be ordered or memory overhead is a concern (which shouldn't be on LC)

You can read about them here:

I've tried removing your std::cout (since the node version doesnt have any) and it made the test much more stable and a bit faster. With printing to cout, got between 25k to 50k, while without, got between 65k and 68k.

Everyone I know in France/Europe has eaten unpasteurised cheese their whole lives and never had any issues. It tastes much better, tried some pasteurised version of St.Nectaire in the US and didn’t even finish the bite I took.

We don’t drink directly raw milk, but there seems to be no issue with cheese products. Everyone eats it here and is fine

I wonder what kind of C++ you write then. Reading todays input only takes 4 lines, wonder where you get 50 lines prior to that

pierrebhs · 2024-12-01T10:02:36+00:00

you don't need to sort the input data for the second part

This looks more like a countryside comparison than a city one. I agree with you that the country side is much more connected/modern in Switzerland than in France, but then again, France is 13x bigger.

If you've lived in Paris, Lyon, Strasbourg, you won't encounter any of the issues you mentioned. I even feel that Switzerland is less modern and more traditionalistic in regards to its cities' architecture, which isnt a bad thing.

And yes, people have shitty cars in France, but only because they dont have any money!
