using namespace std;

int main() {
  vector<int> v = {1, 2, 3, 4, 5};
  for(int i=0; i<v.size(); i++) {
    cout << v[i] << " ";
  }
  cout << endl;
}

#include <iostream>

using namespace std;

int main() {
  vector<int> v = {1, 2, 3, 4, 5};
  vector<int>::iterator it;
  for(it=v.begin(); it<v.end(); it++) {
    cout << *it << " ";
  }
  cout << endl;
}
