Why, a fairer comparison of C and C++ is to compile the C as C++ >I don't think that makes musch difference between C++ and C. Yes it does, or certainly would do with objects. 'j' would be constructed (and destructed) 10000 times and 'k' 100000 times. That said the C++ is still slower 22s (25s using your code) compared to 16s (on my system). -- James Undery <james AT ghoti DOT demon DOT co DOT uk>
