Does C++11 have wrappers for dynamically-allocated arrays like Boost's scoped_array?

Question

I often need to deal with dynamically-allocated arrays in C++, and hence rely on Boost for scoped_array, shared_array, and the like. After reading through Stroustrup\'s C++1

Answer 1

There is a specialization of unique_ptr, like unique_ptr<T[]>.

#include <iostream>
#include <memory>

struct test
{
  ~test() { std::cout << "test::dtor" << std::endl; }
};

int main()
{
  std::unique_ptr<test[]> array(new test[3]);
}

When you run it, you will get this messages.

test::dtor
test::dtor
test::dtor

If you want to use shared_ptr, you should use std::default_delete<T[]> for deleter since it doesn't have one like shared_ptr<t[]>.

std::shared_ptr<test> array(new test[3], std::default_delete<test[]>());

So far as vectors are intended as array wrappers, what if you use any suitable smart pointer with the vector as inner object?
