Use pop_back() and empty().


#include <iostream>
#include <vector>
using namespace std;

int main()
{
  vector<char> vectorObject;
  int i;

  for(i = 0; i <10; i++)
    vectorObject.push_back(i + 'A');

  cout << "Vector's original contents:\n";
  for(i = 0; i <vectorObject.size(); i++)
    cout << vectorObject[i] << " ";

  cout << "\n\n";

  do {
    vectorObject.pop_back(); // remove an element from the end

    cout << "Vector now contains:\n";
    for(i = 0; i <vectorObject.size(); i++)
      cout << vectorObject[i] << " ";
    cout << endl;

  } while(!vectorObject.empty());

  return 0;
}
