#include<iostream>
#include<vector>
#include<algorithm>
using namespace std;

template <typename T>
class print{
public:
 void operator()(const T& elem)
 {
      cout<<elem<<' ';
 }
};

int main()
{
 int ia[6]={0,1,2,3,4,5};
 vector<int> iv(ia,ia+6);
 for_each(iv.begin(),iv.end(),print<int>());
 cout<<endl;
 system("pause");
