// A C++ program to demonstrate working of sort(),
// reverse()
#include <algorithm>
#include <iostream>
#include <vector>
#include <numeric> //For accumulate operation
using namespace std;
 
int main()
{
    // Initializing vector with array values
    int arr[] = {10, 20, 5, 23 ,42 , 15};
    int n = sizeof(arr)/sizeof(arr[0]);
    vector<int> vect(arr, arr+n);
 
    cout << "Vector is: ";
    for (int i=0; i<n; i++)
        cout << vect[i] << " ";
 
    // Sorting the Vector in Ascending order
    sort(vect.begin(), vect.end());
 
   
    cout << "\nVector after sorting is: ";
    for (int i=0; i<n; i++)
       cout << vect[i] << " ";
 
   
      // Sorting the Vector in Descending order
      sort(vect.begin(),vect.end(), greater<int>());
   
    cout << "\nVector after sorting in Descending order is: ";
    for (int i=0; i<n; i++)
       cout << vect[i] << " ";
   
   
    // Reversing the Vector (descending to ascending , ascending to descending)
    reverse(vect.begin(), vect.end());
 
    cout << "\nVector after reversing is: ";
    for (int i=0; i<n; i++)
        cout << vect[i] << " ";
 
    cout << "\nMaximum element of vector is: ";
    cout << *max_element(vect.begin(), vect.end());
 
    cout << "\nMinimum element of vector is: ";
    cout << *min_element(vect.begin(), vect.end());
 
    // Starting the summation from 0
    cout << "\nThe summation of vector elements is: ";
    cout << accumulate(vect.begin(), vect.end(), 0);
 
    return 0;
}
Vector is: 10 20 5 23 42 15 
Vector after sorting is: 5 10 15 20 23 42 
Vector after sorting in Descending order is: 42 23 20 15 10 5 
Vector after reversing is: 5 10 15 20 23 42 
Maximum element of vector is: 42
Minimum element of vector is: 5
The summation of vector elements is: 115
