- 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:
// CPP program to demonstrate the
// multiset::rbegin() function
#include <bits/stdc++.h>
using
namespace
std;
int
main()
{
int
arr[] = { 15, 12, 15, 11, 10, 10 };
// initializes the set from an array
multiset<
int
> s(arr, arr + 6);
multiset<
int
>::reverse_iterator rit;
// prints all elements in reverse order
for
(rit = s.rbegin(); rit != s.rend(); rit++)
cout << *rit <<
" "
;
cout <<
"\nThe last element in multiset is "
<< *(s.rbegin());
return
0;
}

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:
// CPP program to demonstrate the
// multiset::rend() function
#include <bits/stdc++.h>
using
namespace
std;
int
main()
{
int
arr[] = { 15, 13, 15, 11, 13, 10 };
// initializes the set from an array
multiset<
int
> s(arr, arr + 6);
multiset<
int
>::reverse_iterator rit;
// prints all elements in reverse order
for
(rit = s.rbegin(); rit != s.rend(); rit++)
cout << *rit <<
" "
;
return
0;
}
chevron_rightfilter_noneOutput:15 15 13 13 11 10
