       constexpr shared_ptr () noexcept
           Construct an empty shared_ptr.
       template<typename _Yp , typename  = _Constructible<_Yp*>> shared_ptr (_Yp *__p)
           Construct a shared_ptr that owns the pointer __p.
       template<typename _Yp , typename _Deleter , typename  = _Constructible<_Yp*, _Deleter>> shared_ptr (_Yp
           *__p, _Deleter __d)
           Construct a shared_ptr that owns the pointer __p and the deleter __d.
       template<typename _Yp , typename _Deleter , typename _Alloc , typename  = _Constructible<_Yp*, _Deleter,
           _Alloc>> shared_ptr (_Yp *__p, _Deleter __d, _Alloc __a)

           If __r is empty, constructs an empty shared_ptr; otherwise construct a shared_ptr that shares
           ownership with __r.
       template<typename _Yp > shared_ptr (const shared_ptr< _Yp > &__r, element_type *__p) noexcept
           Constructs a shared_ptr instance that stores __p and shares ownership with __r.

           > &__r)
           Constructs a shared_ptr that shares ownership with __r and stores a copy of the pointer stored in
           __r.

           Construct a shared_ptr that owns a null pointer and the deleter __d.

Detailed Description

   template<typename _Tp>
       class std::shared_ptr< _Tp >" A smart pointer with reference-counted copy semantics.

       The object pointed to is deleted when the last shared_ptr pointing to it is destroyed or reset.
