how to print elements of vector in reverse order in cpp code example

Example 1: how to sort a vector in reverse c++

#include <iostream>
#include <vector>
#include <algorithm>
using namespace std;
int main() {
   vector<int> v = { 10, 9, 8, 6, 7, 2, 5, 1 };
   sort(v.begin(), v.end(), greater <>());
}

Example 2: how to reverse a vector

//vector<int> A;
reverse(A.begin(),A.end());

Example 3: reverse a vector

vector<int> a = {1,2,3,4,5,6};
reverse(a.begin(), a.end());
