Dynamically allocated arrays or std::vector

Question

I\'m trying to optimize my C++ code. I\'ve searched the internet on using dynamically allocated C++ arrays vs using std::vector and have generally seen a recommendation in f

Answer 1

Just for fun, try iterating over the plain array using a pointer instead of an integer index (the code should look just like the vector iteration, since the point of STL iterators is to appear like pointer arithmetic for most operations). I bet the speed will be exactly equal in that case. Which of course means you should pick the vector, since it will save you a world of headaches from managing arrays by hand.
