explicit auto_ptr(T *p = 0) throw();
auto_ptr(const auto_ptr(auto_ptr<T>& rhs) throw();The first constructor stores p as the pointer to the allocated object. It stores true as the ownership indicator only if p
!= 0. The second constructor transfers ownership of the pointer stored in rhs, by storing both the pointer value and
the ownership indicator from rhs in the constructed object. It effectively releases the pointer by calling
rhs.release().
In this implementation, if a translator does not support member template functions, the template:
template<class U>
auto_ptr(const auto_ptr(auto_ptr<U>& rhs) throw();is replaced by:
auto_ptr(const auto_ptr(auto_ptr<T>& rhs);
