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

int main() 
{
    vector <int> v;
    for(int i = 1; i <= 5; i++)
            v.push_back(i);
       
    for(int i = 1; i <= 5; i++)
      {
          if(v[i] % 2 == 0)    // line 1
          cout << v[i] << \" \";
      }
    return 0;
} 

Output of the above program will be
(A) 2 4
(B) 0 2 4
(C) 2 4 0
(D) None of the mentioned


Answer: (C)

Explanation:
v[index] returns the reference to the element present at index of vector \’v\’. So there is no error in the line 1.
Elements in the vector are as such:

v[0] = 1
v[1] = 2
v[2] = 3
v[3] = 4
v[4] = 5

So the for traverses and prints the even elements in the vector, element present at v[5] = 0 is also printed.
