New members

These members are not defined in the Assignable requirements, but are specific to pair.

Member	Description
first_type	The type of the pair's first component. This is a typedef for the template parameter T1
second_type	The type of the pair's second component. This is a typedef for the template parameter T2
pair()	The default constructor. It uses constructs objects of types T1 and T2 using their default constructors. This constructor may only be used if both T1 and T2 are DefaultConstructible.
pair(const first_type& x, const second_type& y)	The pair constructor. Constructs a pair such that first is constructed from x and second is constructed from y.
first	Public member variable of type first_type: the first object stored in the pair.
second	Public member variable of type second_type: The second object stored in the pair.
