public member function
<valarray>
Valarray destructor
Destroys the valarray after calling each of the contained elements' destructors (if any).
Complexity
Depends on library implementation (operations may be parallelized).
Iterator validity
Invalidates all iterators, references and sub-arrays of the valarray.
Data races
The object and all its contained elements are destroyed.
Exception safety
No-throw guarantee: never throws exceptions.
