Use back_insert_iterator to insert element into a vector

  
 

#include <iostream>
#include <vector>
#include <algorithm>
#include <iterator>

using namespace std;

int main( ) {

   vector<int> v;
   back_insert_iterator<std::vector<int> > p = back_inserter(v);

   for (int i = 0; i < 10; ++i)
     *p = i;

   for (int i = 0; i < 10; ++i){
       cout << v[i];
   }

   cout << "\n\n\n";
   random_shuffle(v.begin( ), v.end( ));

   for (int i = 0; i < 10; ++i){
       cout << v[i];
   }
