      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.
