Look at the kernel code. It’s full of OOP C. There absolutely are objects in the kernel.

Yea but all that function pointer indirection can actually hurt performance (especially caching), some things in C++ actually can be faster just because the compiler is better at optimizing for that.

There is nothing you can do in C++ or C, that can’t be done in the other. It’s the kind of the point of those languages.

Technically you’re right, but I don’t think that changes what I said about optimization. There are still cases where equivalent C++ code can be faster than the C version merely due to different optimizations used.

Meh, I’m unconvinced. If it’s any kind of hot spot, in either, you can optimize the hell out of it. C++ is often more bloated is it’s just a harder language pretending to be an easier one.

That’s fine, you don’t have to agree. Personally I do like to use just a few features of C++ without going too crazy, like simple classes and maybe one level of inheritance, but I don’t really get into templates or exceptions or other really complex/controversial stuff. I prefer having the stronger typing and better readability of this kind of C++, and I think it helps me make less mistakes, but I realize not everyone agrees, and that’s ok.

I think that’s the thing, C++ is so broad. It’s like many languages together. It’s complex with lots of implicitness yet unsafe. There is loads of support in compilers and tools to mitigate that, but that’s treatment not cure.
