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

int main()
{
    vector<int> data(5,1);
    int sum {0};

    cout << sum << endl;
    
    for(auto element : data)
         sum += element;
    cout << sum << endl;

    for(auto p = ++data.begin(); p != --data.end(); ++p)
         sum += *p;
    cout << sum << endl;
  
    sum = 0;
    data.push_back(2);
    data.push_back(3);
    
    for(auto element : data)
         sum += element;
    cout << sum << endl;

    cout << accumulate(data.begin(), data.end(), data[0]) << endl;
}

MY question is :

What does the first line of the following print?
What does the Second line of the following print?
What does the Third line of the following print?
What does the Fourth line of the following print?
What does the fifth line of the following print?

Hey @Raghav-Khemka

I am confused. Have you tried running it? Are you asking what the output would be if you ran it?
