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.

#include 
#include 

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

int main()
{
  std::unique_ptr 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 for deleter since it doesn't have one like shared_ptr.

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