A prvalue of type T can be converted to an xvalue of type T[.](#1.sentence-1)
|
||
|
||
This conversion initializes a temporary object ([[class.temporary]](class.temporary "6.8.7 Temporary objects")) of type T from the prvalue
|
||
by evaluating the prvalue with the temporary object as its result object,
|
||
and produces an xvalue denoting the temporary object[.](#1.sentence-2)
|
||
|
||
T shall be a complete type[.](#1.sentence-3)
|
||
|
||
[*Note [1](#note-1)*:
|
||
|
||
If T is a class type (or array thereof),
|
||
it must have an accessible and non-deleted destructor;
|
||
see [[class.dtor]](class.dtor "11.4.7 Destructors")[.](#1.sentence-4)

[*Example [1](#example-1)*: struct X { int n; };int k = X().n; // OK, X() prvalue is converted to xvalue â *end example*]
