90% of statistics are plucked from the air, including that one.With C++ this fits. Most abstractions don't have an additional overhead
over a manual implementation.
There are quite a lot of places in low level programming where you have to manage without them. Sometimes you have to do without the runtime as well. That doesn't mean you can't use C++ itself.As I said, you have no idea what you are talking about in the context of low-level programming.I told you why it isn't practicable to suppress exceptions in C++
since the runtime uses a lot of exceptions.
The vast majority of processors in desktop computers and above, sure. But do you think the one in my watch has one? My thermostat? The alarm clock? I've got at least a dozen devices with processors in this room with me right now.Again, you demonstrate your total ignorance of the topic.Most of the time a nanosecond more doesn't count, especiailly because
usually you do more complex things in a virtual function.
The vast majority of processors produced and sold do not have any kind of branch prediction.Not today.
