multimap::rbegin() method in C++ STL

Multimaps are associative containers available in the C++ Standard Library. They are similar to a map with an addition that multiple elements can have the same keys. The multimap::rbegin() is a method available in the STL that returns a reverse iterator to the last element in the container.

Syntax:

map_name.rbegin();

Parameters: The multimap::rbegin() does not accept any parameter:
Return value: Reverse iterator to the last element in the container

Example of multimap::rbegin() method

#include<iostream>
#include<map>

using namespace std;


int main()
{
    multimap<char,int> m;

    m.insert( pair<int,int> ('a',1) );
    m.insert( pair<int,int> ('b',2) );
    m.insert( pair<int,int> ('c',3) );
    m.insert( pair<int,int> ('d',4) );

    multimap<char, int>::reverse_iterator it = m.rbegin();
    cout<<"last element: \n";
    cout<< it->first << " : "<< it->second<<endl;
}

Output:

last element:
d
