std::swap(std::array) 

template< class T, std::size_t N >
void swap( array<T,N>& lhs, 
           array<T,N>& rhs );
 (since C++11)
(until C++17) 
template< class T, std::size_t N >
void swap( array<T,N>& lhs, 
           array<T,N>& rhs ) noexcept(/* see below */);
 (since C++17)

Specializes the std::swap algorithm for std::array. Swaps the contents of lhs and rhs. Calls lhs.swap(rhs).

This overload only participates in overload resolution if N == 0 or std::is_swappable<T>::value is true.

 (since C++17)

Parameters

lhs, rhs - containers whose contents to swap

Return value

(none).

Complexity

Linear in size of the container.

Exceptions

noexcept specification:
noexcept(noexcept(lhs.swap(rhs)))
 (since C++17)
