list rbegin() and rend() function in C++ STL

Last Updated : 17 Jul, 2018

list::rbegin() is an inbuilt function in C++ STL that returns a reverse iterator which points to the last element of the list.

Syntax:

list_name.rbegin()

Parameter: This function does not accept any parameters.

Return value: It returns a reverse iterator which points to the last element of the list.

Below program illustrates the above function:

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

Output:

The list in reverse order: 50 40 30 20 10

list::rend() is an inbuilt function in C++ STL that returns a reverse iterator which points to the position before the beginning of the list.

Syntax:

list_name.rend()

Parameter: The function does not accept any parameters.

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

Below program illustrates the above function:

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

Output:

The list in reverse order: 50 40 30 20 10
