#include <iostream>
#include <vector>
#include <list>
#include <algorithm>

using std::cout;
using std::endl;
using std::list;
using std::vector;

bool IsEven(int n) { return ((n % 2) == 0); }

int main()
{
	list<int> lst{ 1,2,3,4,5,6,7,8,9 };
	vector<int> vec(9);

	std::remove_copy_if(lst.begin(), lst.end(), vec.begin(), IsEven);

	for (vector<int>::iterator p = vec.begin(); p != vec.end(); p++)
		cout << *p << ' ';

	cout << endl;
