Defined in header <complex> 
template< std::size_t I >
friend constexpr T& get( std::complex<T>& x );
 (1) (since C++26) 
template< std::size_t I >
friend constexpr const T& get( const std::complex<T>& x );
 (2) (since C++26) 
template< std::size_t I >
friend constexpr T&& get( std::complex<T>&& x );
 (3) (since C++26) 
template< std::size_t I >
friend constexpr const T&& get( const std::complex<T>&& x );
 (4) (since C++26)

Parameters

x - a complex

Return value

1-4) A reference to the real or imaginary part from the stored one when I == 0 or I == 1, respectively.
