Re: strange behaviour of vector iterator

hi,

i was using vector template when i found out a strange thing, i
managed to restrict the 'bug' in this code:

#include <cstdlib>
#include <iostream>
#include <vector>

using namespace std;

vector<int>::iterator _begin(vector<int> v){
    return v.begin();

}

int main(int argc, char *argv[])
{
    vector<int> v;
    v.push_back(4);
    vector<int>::iterator b = _begin(v);
    printf("%d\n",*b);
    printf("%d\n",*_begin(v));

    system("PAUSE");
    return EXIT_SUCCESS;

}

actually output is the following:
0
4

while i was expecting:
4
4

i can't understand what happen wrong in the assignment
