copy
Description

Copy a sequence src to a sequence dest. It is also used to convert sequence into other.

Synopsis
template <typename Seq1, typename Seq2>
void copy(Seq1 const& src, Seq2& dest);

Table 1.37. Parameters

Parameter

Requirement

Description

src

A model of Forward Sequence, all elements contained in the src sequence should be convertible into the element contained in the dest sequence.

Operation's argument

dest

A model of Forward Sequence, e2 = e1 is valid expression for each pair of elements e1 of src and e2 of dest.

Operation's argument


Expression Semantics
copy(src, dest);

Return type: void

Semantics: e2 = e1 for each element e1 in src and e2 in dest.

Complexity

Linear, exactly result_of::size<Sequence>::value.
