c++ sort in descending order 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 sort in descending order c++

int arr[10];
int length = sizeof(arr)/sizeof(arr[0]); 
sort(arr, arr+length, greater<int>());
