Detailed Description
The QScopedArrayPointer class stores a pointer to a dynamically allocated array of objects, and deletes it upon destruction.
A QScopedArrayPointer is a QScopedPointer that defaults to deleting the object it is pointing to with the delete[] operator. It also features operator[] for convenience, so we can write:
void foo() { QScopedArrayPointer<int> i(new int[10]); i[2] = 42; ... return; // our integer array is now deleted using delete[] }
