例

このコードを実行します

#include <vector>#include <iostream>#include <algorithm>   int main(){std::vector<int> v({1,2,3});std::for_each(std::begin(v), std::end(v), [&](int value){std::cout<< value <<" ";});std::cout<<std::endl;   std::vector<int> destiny(3); std::reverse_copy(std::begin(v), std::end(v), std::begin(destiny));std::for_each(std::begin(destiny), std::end(destiny), [&](int value){std::cout<< value <<" ";});std::cout<<std::endl;}

出力:

1 2 3 3 2 1
