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

Last Updated : 12 Jun, 2023

multiset::rbegin() is a built-in function in C++ STL which returns a reverse iterator pointing to the last element in the multiset container. 

Syntax:

reverse_iterator multiset_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. 

Below program illustrate the multiset::rbegin() method: 

Output:
15 15 12 11 10 10 
The last element in multiset is 15

multiset::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 multiset container. 

Syntax:

reverse_iterator multiset_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 multiset container. 

Below program illustrate the multiset::rend() function: 

Output:
15 15 13 13 11 10

Let us see the differences in a tabular form -:

multiset rbegin() multiset rend() 
1.It is used to return a reverse iterator pointing to the last element in the containerIt is used to return a reverse iterator pointing to the theoretical element right before the first element in the multiset container 
2.

Its syntax is -:

reverse_iterator rbegin();

Its syntax is -:

reverse_iterator rend();

3.It does not take any parameters.It does not take any parameters.
4.Its complexity is constant.Its complexity does not changes.
5.Its iterator validity does not changes.Its iterator validity does not change.
