WebJun 23, 2005 · boost::scoped_array< int > pie_sa ( new int [31415] ); Advantages of the former include: 1) much better preformance during a resize (which for a scoped array would involve allways reallocating) 2) as std::vector tracks how much it allocates, there's the potential for a more optimized deallocation of the associated data on destruction. WebSee shared_array if scoped_array does not meet your needs. It cannot correctly hold a pointer to a single object. See scoped_ptr for that usage. A std::vector is an alternative to a scoped_array that is a bit heavier duty but far more flexible. A boost::array is an alternative that does not use dynamic allocation.
