Get the last n items from a vector in C++

Given a vector in C++, we have to get the last n items from it.

For example,

The given vector is

Digits={5,8,9,11,15,20}

Input: n=2

Output: 15 20

To access the last n elements we have to use the size of vector.

Let’s understand this with help of a code.

#include <iostream>
#include <vector>
using namespace std;
int main()
{
    vector<int> Digits {5,8,9,11,15,20};
   
    int length = Digits.size();    // Get number of elements in vector
    int n=2;
    for(int i=length-n;i<length;i++)
    cout<<Digits[i]<<" ";
    return 0;
}

Output:

15 20
