Algorithm - reverse_copy()

원형)

template <class BidirectionalIterator, class OutputIterator>
  OutputIterator reverse_copy (BidirectionalIterator first,
                               BidirectionalIterator last, OutputIterator result);

의미)

[Iterator first, Iterator last)사이의 데이터를 역순으로 Iterator result가 가리키는 곳부터 삽입합니다.

소스)

#include<iostream>
#include<algorithm>
#include<vector>
 
void Print(const std::vector<int>& target)
{
    for (std::vector<int>::const_iterator iterPos = target.begin(); iterPos != target.cend(); iterPos++)
        std::cout << *iterPos << ' ';
    std::cout << std::endl;
}
 
void main()
{
    std::vector<int> vector = { 1,3,5,4,3,2,6,7,9,11 };
    std::vector<int> vectorCopy(10);
    std::cout << "Vector--->"; Print(vector);
    std::cout << "VectorCopy--->";Print(vectorCopy);
    std::reverse_copy(vector.begin(), vector.end(), vectorCopy.begin());
    std::cout << "Vector--->"; Print(vector);
    std::cout << "VectorCopy--->";Print(vectorCopy);
}

리턴값)

복사된 범위의 마지막을 가리키는 Iterator를 리턴합니다.
