What will happen when you attempt to compile and run the following code?

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

using namespace std;
void
printer(int v)
{
  cout<<v<<", ";
}
struct Sequence
{
  int start;
  Sequence(int start):start (start){}
  int operator() ()
  {
    return start++; //LINE I
  }
};

int
main()
{
  vector<int> v1(5);
  generate_n(v1.begin(), 5, Sequence(5)); //LINE II
  for_each(v1.begin(), v1.end(), printer);
  return 0;
}

• compilation error in LINE I
• the program outputs 5, 5, 5, 5, 5,
• compilation error in LINE II
• the program outputs 5, 6, 7, 8, 9,
• the program outputs 1, 2, 3, 4, 5,
• runtime error at LINE II
