copy_n
Prototype

template<class SinglePassRange, class Size, class OutputIterator>
OutputIterator copy_n(const SinglePassRange& rng, Size n, OutputIterator out);

Description

copy_n is provided to completely replicate the standard algorithm header, it is preferable to use Range Adaptors and the extension functions to achieve the same result with greater safety.

copy_n copies elements from [boost::begin(rng), boost::begin(rng) + n) to the range [out, out + n)

Definition

Defined in the header file boost/range/algorithm_ext/copy_n.hpp

Requirements
  1. SinglePassRange is a model of the Single Pass Range Concept.
  2. Size is a model of the Integer Concept.
  3. OutputIterator is a model of the OutputIteratorConcept.
Complexity

Linear. Exactly n elements are copied.
