Is there a heap allocated fixed-size array in the standard library?

I am looking for the equivalent of .NET fixed size arrays in C++ and am having real trouble finding this information by Googling it. std::array imitates Pascal by having the length embedded directly in its type. std::vector is good, but passes around 3 pointers on the stack where I'd prefer just one.

Also rather than iterator based arrays, since I am working on a C++ backend for a functional language I'd prefer it to be size based so as too match the arrays in the .NET and the Cython backends.

Should I implement my own array class instead?

Edit: What I am asking for is a flexible array (such as this one) as a part of a library.

You can use unique_ptr:

#include <memory>

int main() {
  // note brackets  vvvv
  std::unique_ptr<int[]> arr{ new int[42] };
  arr[0] = 13;
  // ...
}
