The TR1 Tuple type provides a default constructor, a constructor that takes initializers for all of its elements, a copy constructor, and a converting copy constructor. The details of the various constructors are described in this section.

Tuple element types
Parameter types
The type of the ith element of a tuple
The type of the ith parameter
tuple();
Requirements: Each Ti is default constructable.
Semantics: Default initializes each element of the tuple.
tuple(P1,P2,...,PN);
Requirements: Each Pi is Ti if Ti is a reference type, const Ti& otherwise.
Semantics: Copy initializes each element with the corresponding parameter.
tuple(const tuple& t);
Requirements: Each Ti should be copy constructable.
Semantics: Copy constructs each element of *this with the corresponding element of t.
template<typename U1, typename U2, ..., typename UN> tuple(const tuple<U1, U2, ..., UN>& t);
Requirements: Each Ti shall be constructible from the corresponding Ui.
Semantics: Constructs each element of *this with the corresponding element of t.
