    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.

                I think the same could be said about C now too, it is continuing to evolve itself with newer standards too just like C++. People choose to only use C features that they want, same goes for C++.

                  And that is true of any language, but C++ is without doubt one of the broadest. There are very different ways of working with it that compile very differently.
