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

enum response { a,

                c,
                d, 
                e };

int main() {
  multiset<response> question;

  // create some responses
  question.insert(response(a));
  question.insert(response(b));
  question.insert(response(c));
  question.insert(response(c));
  question.insert(response(d));
  question.insert(response(d));
  question.insert(response(d));
  question.insert(response(d));

  // display results
  cout << "a: ";
  cout << question.count(a) << endl;

  cout << "b: ";
  cout << question.count(b) << endl;

  cout << "c: ";
  cout << question.count(c) << endl;

  cout << "d: ";
  cout << question.count(d) << endl;

  return 0;
