using namespace std;
void show(const char *msg, vector<char> vect);
int main() {//ww  w  .  ja v a2  s  .  c o m
   // Declare an empty vector that can hold char objects.
   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();
   // Declare a reverse iterator.
   vector<char>::reverse_iterator ritr;
   // Use a reverse iterator to show the contents of v in reverse.
   cout << "Here is v in reverse: ";
   for(ritr = v.rbegin(); ritr != v.rend(); ++ritr)
      cout << *ritr << " ";
   cout << "\n\n";
   return 0;
