Randomize elements in a vector with random_shuffle(scores.begin(), scores.end());

  
#include <iostream>
#include <vector>
#include <algorithm>
#include <ctime>
#include <cstdlib>

using namespace std;

int main()
{
    vector<int>::const_iterator iter;

    vector<int> scores;
    scores.push_back(1);
    scores.push_back(3);
    scores.push_back(5);

    for (iter = scores.begin(); iter != scores.end(); ++iter)
        cout << *iter << endl;

    srand(time(0));
    random_shuffle(scores.begin(), scores.end());
    for (iter = scores.begin(); iter != scores.end(); ++iter)
        cout << *iter << endl;

 return 0;
