What are you trying to say? C++ can be just as safe as Rust. The latter is just easier to use, especially in terms of working as a team of developers insomuch as the safety-nets are by default in place. Once again, C++ is powerful but comes with just as many footguns as C (in fact, more) and so requires a bit more finesse, experience, and skill to work with safely. Otherwise it can encapsulate pretty much any functionality you could possibly imagine, and that includes safety features. Checked memory accesses, managed memory, well-behaved arithmetic, all of that and more can be codified as a set of objects and interfaces. I started out in assembler, worked up to C, then finally on to C++ where I actually found it quite easy to write safe programs by just sticking to a strict set of guidelines. And that works. I have code that has been running almost continuously for over a decade without a hitch, and I credit that to good programming practices.
