C++ valarray vs. vector
... pointers so the compiler can make assumptions about the code and optimise it better. (The main reason that Fortran is so fast is that there is no pointer type so there can be no pointer aliasing.)

Here's a detailed explanation which I hope will be helpful. Let's begin with your program, as it's the simplest to explain.
