Why use one against the other: `boost :: shared_array` VS` boost :: shared_ptr <std :: vector>`?

Thus, in order to deal with large blocks of memory for an image or the like, there are many options.

Since I'm a fan of smart pointers and RAII, I wonder what it is smarter with:

  • a shared_ptrtostd::vector

or

  • go with shared_arraypointing to a dynamically allocated array.

What are the conceptual, practical, and operational consequences of choosing one and the other?

This is the same as comparing the std :: vector array against C.
