The problem with c++ is that it allows people to do whatever they want. Turns out: people are dumb. Rust solved that problem. Nothing more, nothing less.
Rust still allows people to do (basically) whatever they want via unsafe blocks.
Yeah but I have written a lot of Rust and I have yet to use a single
unsafeblock.Saying "but.. unsafe!" is like saying Python isn't memory safe because it has
ctypes, or Go isn't memory safe because of itsunsafepackage.You don't have to use unsafe C++ functions either
C++ is technically safe if you follow best practices
The issue, to me, is that people learn older versions of the language first, and aren't aware of the better ways of doing stuff.
IMO people should learn the latest C++ version first, and only look at the older types of implementation when they come across them
Yeah but it's virtually impossible to reliably follow best practices. The compiler won't tell you when you're invoking UB and there is a lot of potential UB in C++.
So in practice it is not at all safe.
I agree
I was only adding my opinion (that people should try to always use the latest version of C++, which is inherently safer, but still not 100% safe)
