Demonstrate insert_iterator

using namespace std;
int main() {
vector<int> v;
vector<int>::iterator itr;
for(int i=0; i<5; i++)
v.push_back(i);

cout << endl;
itr = v.begin();
itr += 2; // point to element 2
// create insert_iterator to element 2
insert_iterator<vector<int> > i_itr(v, itr);
// insert rather than overwrite
*i_itr++ = 100;
*i_itr++ = 200;
cout << "Array after insertion: ";

}
/*
Original array: 0 1 2 3 4
Array after insertion: 0 1 100 200 2 3 4
