C++ Question

Is there any use for unique_ptr with array?

has support for arrays, for instance:

std::unique_ptr<int[]> p(new int[10]);

but is it needed? probably it is more convenient to use

Do you find any use for that construct?


Some people do not have the luxury of using std::vector, even with allocators. Some people need a dynamically sized array, so std::array is out. And some people get their arrays from other code that is known to return an array; and that code isn't going to be rewritten to return a vector or something.

By allowing unique_ptr<T[]>, you service those needs.

In short, you use unique_ptr<T[]> when you need to. When the alternatives simply aren't going to work for you. It's a tool of last resort.
