16.19.6.Obtain an iterator to the start of vector
#include <iostream>
#include <vector>

using namespace std;

void show(const char *msg, vector<char> vect);

int main() {
  vector<char> v;

  // Declare an iterator to a vector<char>.
  vector<char>::iterator itr;

  // Obtain an iterator to the start of v.
  itr = v.begin();


  return 0;
}

void show(const char *msg, vector<char> vect) {
  vector<char>::iterator itr;

  cout << msg << endl;
  for(itr=vect.begin(); itr != vect.end(); ++itr)
    cout << *itr << endl;
