Subclause [[tuple]](tuple "22.4 Tuples") describes the tuple library that provides a tuple type as
|
||
the class template tuple that can be instantiated with any number
|
||
of arguments[.](#1.sentence-1)
|
||
|
||
Each template argument specifies
|
||
the type of an element in the tuple[.](#1.sentence-2)
|
||
|
||
Consequently, tuples are
|
||
heterogeneous, fixed-size collections of values[.](#1.sentence-3)
|
||
|
||
An instantiation of tuple with
|
||
two arguments is similar to an instantiation of pair with the same two arguments[.](#1.sentence-4)
|
||
|
||
See [[pairs]](pairs "22.3 Pairs")[.](#1.sentence-5)
