element_type& operator( std::ptrdiff_t idx ) const;
Index into the array pointed to by the stored pointer.
The behavior is undefined if the stored pointer is null or if
idx is negative.
T (the template parameter of
shared_ptr) is an array type
idx must be less than
N, otherwise the behavior is undefined.
|idx||-||the array index|
A reference to the
idx-th element of the array, i.e., get()[idx]
T is not an array type, it is unspecified whether this function is declared. If the function is declared, it is unspecified what its return type is, except that the declaration (although not necessarily the definition) of the function is guaranteed to be legal.
