Hi Community !!!
whats the advantages by using C++ against C
unless using Classes in QNX4 and in Neutrino?.
Is there a difference between quickness or is it equal.
In whitch case I should use C++ and in whitch case I should use C
Thank You !!!
C tends to be faster than C++ in most cases, but as always, it depends on what you are writing. Advantages of C++ are basically that of object-orientation, OO is generally considered a good idea in large, complex applications. C however, is generally simpler and quicker, which makes it a good choice for real time applications, device drivers, stuff like that.
I’d say use whatever you are comfortable with, however C is much more popular on QNX than C++, so you’ll likely get more help with C related problems than C++ on forums like this.
Thank you thegman !!!
Well, a couple of the things (that aren’t related to classes) are:
- templates
- exceptions
You could write an entire book about that question, but fundamentally all that can be said is: “it depends”.
Personally, I would always use C++, unless there was a very specific reason why I can’t.

Under QNX4, C code compile with the C++ compiler tends to be up to 10% slower.
That being said I would go with C++ unless speed is paramount.
