Proper way to pass dynamic arrays to other functions

Question

What\'s the most \"proper\" way to pass a dynamically sized array to another function?

bool *used = new bool[length]();

I\'ve come up with

Answer 1

static void test(bool arr[])
static void test(bool *arr, size_t size)

For static/dynamic arrays, if you don't want to change location of this pointer.

Example: http://liveworkspace.org/code/c5e379ebe2a051c15261db05de0fc0a9

static void test(bool *&arr)

For dynamic if you want to change location.

But, since you write on C++ - use vectors, instead of raw dynamic arrays.
