how to sort vector in descending order in c++ 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: sort vector descending

int main() 
{ 
    // Get the vector 
    vector<int> a = { 1, 45, 54, 71, 76, 12 }; 
  
    // Print the vector 
    cout << "Vector: "; 
    for (int i = 0; i < a.size(); i++) 
        cout << a[i] << " "; 
    cout << endl; 
  
    // Sort the vector in descending order 
    sort(a.begin(), a.end(), greater<int>()); 
  
    // Print the reversed vector 
    cout << "Sorted Vector in descendiing order:n"; 
    for (int i = 0; i < a.size(); i++) 
        cout << a[i] << " "; 
    cout << endl; 
  
    return 0; 
}

Example 3: sort vector in descending order

sort(a.begin(), a.end(), greater<int>());
