std::pair::operator=

pair& operator=( const pair& other );	(1)
template< class U1, class U2 > pair& operator=( const pair<U1,U2>& other );	(2)
pair& operator=( pair&& other );	(3)	(since C++11)
template< class U1, class U2 > pair& operator=( pair<U1,U2>&& other );	(4)	(since C++11)

Replaces the contents of the pair.

1) Copy assignment operator. Replaces the contents with a copy of the contents of other.

2) Assigns other.first to first and other.second to second

3) Move assignment operator. Replaces the contents with those of other using move semantics.

4) Assigns std::forward<U1>(p.first) to first and std::forward<U2>(p.second) to second.
