[C++]Problema Vector

[Luc@s]

Per studiare gli iteratori e gli algoritmi generici ho sfornato sto cod:

#include <iostream>
#include <vector>
#include <string>

using namespace std;

vector<int> elabora(vector<int> &elem);

int main()
{
	int def[5]={'1', '3', '9', '4', '7'};
	vector<int> es(5, def);
	elabora(es);
	return 0;
}

vector<int> elabora(vector<int> &elem)
{
	sort(elem.begin(), elem.end());// ordina
	vector<int>::iterator it = elem.begin();// itera e monstra
	for(;it<elem.end();it++)
	{
		cout << *it <<endl;
	}
	return elem;
}

Ma mi da:
