If you have a constant expression like 1 + 2 in your code you can evaluate it at compile time once and avoid computing it at runtime. You can do that with control flow and much more complex language constructs in C++. If you want to know more about that look into C++ template meta programming, constexpr, and constval.
It’s easy to build a well-designed language when you don’t have to work around the mistakes of the past that were too difficult to solve then and too deeply entrenched to change now.
C++ has pretty much no compile-time checks, while Rust’s overengineered syntax allows it’s compiler to catch vast majority of your everyday errors during compilation.
C++ has a lot of terrible language features because it would allow some 8 bit embedded CPU to dynamically change from LSB to MSB ordering in the middle of decoding some input. 🙈
That was the point 20 years ago. These days it is pivoting to compile time functional programming
What does that mean ?

Templates are cool as fuck tho… For like 5 minutes until you go insane
I get that the designers wanted to have compile time static replacement but this was not the way to do it.
yeah, zig and rust have the same concepts but much better thought and structed

yes, thats why I dont bother finnishing projects
To be fair, I never fully understood why programming projects have to be native Finlanders, in the end.
Translation: “We’ve made the preprocessor a first-class language feature!”
(jk, don’t kill me)
thank you !
it means rust is cool as fuck
aren’t they talking about C++ ?

ok thanks
Rust is a very modern alternative to C /C++.
Overengineered mess

does anyone actually follow whatver the comittee sees as best practices?
I think the closest to an actual answer you will find are the cpp core guidelines.
