#include <iostream>

#include <vector>

#include <cctype>

using namespace std;



int main()

  vector<char> v(10); // create a vector of length 10



  cout << "Size = " << v.size() << endl;



  for(int i=0; i<10; i++) 

     v[i] = i + 'a';



  cout << "Current Contents:\n";

  for(int i=0; i<v.size(); i++) cout << v[i] << " ";
