Constructor &; Destructor Documentation
template<class _T1, class _T2> constexpr std::pair< _T1, _T2 >::pair () [inline]
second is a copy of the second object The default constructor creates first and second using their respective default constructors.
Definition at line 99 of file stl_pair.h.
template<class _T1, class _T2> constexpr std::pair< _T1, _T2 >::pair (const _T1 &__a, const _T2 &__b) [inline]
Two objects may be passed to a pair constructor to be copied.

template<class _T1, class _T2> template<class _U1 , class _U2 > constexpr std::pair< _T1, _T2 >::pair (const pair< _U1, _U2 > &__p) [inline]
There is also a templated copy ctor for the pair class itself.
