set::rbegin() and set::rend() in C++ STL

Last Updated : 19 Jun, 2018

set::rbegin() is a built-in function in C++ STL which returns a reverse iterator pointing to the last element in the container. Syntax:
```
reverse_iterator set_name.rbegin()
```
Parameters: The function does not take any parameter. Return value: The function returns a reverse iterator pointing to the last element in the container. Program to demonstrate the set::rbegin() method: Program 1:
Output:
```
15 14 12 11 10 
The last element in set is 15
```

set::rend() in an inbuilt function in C++ STL which returns a reverse iterator pointing to the theoretical element right before the first element in the set container. Syntax:
```
reverse_iterator set_name.rend()
```
Parameter: The function does not accepts any parameter. Return value: The function returns a reverse iterator pointing to the theoretical element right before the first element in the set container. Below programs illustrate the function: Program 1:

Output:

5 4 3 2 1
