deque rend() function in C++ STL
  • Difficulty Level : Basic
  • Last Updated : 30 Aug, 2018

The deque::rend() is an inbuilt function in C++ STL which returns a reverse iterator which points to the position before the beginning of the deque (which is considered its reverse end).

Syntax:

deque_name.rend()

Parameter: This function does not accept any parameters.

Return value: It returns a reverse iterator which points to the position before the beginning of the deque.

Below program illustrates the above function:



Program 1:




// C++ program to illustrate the
// deque::rend() function
#include <bits/stdc++.h>
using namespace std;
  
int main()
{
    deque<int> dq = { 10, 20, 30, 40, 50 };
  
    cout << "The deque in reverse order: ";
  
    // prints the elements in reverse order
    for (auto it = dq.rbegin(); it != dq.rend(); ++it)
        cout << *it << " ";
  
    return 0;
}


Output:

The deque in reverse order: 50 40 30 20 10

Program 2:




// C++ program to illustrate the
// deque::rend() function
#include <bits/stdc++.h>
using namespace std;
  
int main()
{
    deque<char> dq = { 'a', 'b', 'c', 'd', 'e' };
  
    cout << "The deque in reverse order: ";
  
    // prints the elements in reverse order
    for (auto it = dq.rbegin(); it != dq.rend(); ++it)
        cout << *it << " ";
  
    return 0;
}


Output:

The deque in reverse order: e d c b a
