multimap::find() 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::find() is a method available in the STL that searches the map and returns an iterator to the first occurrence of a specific key if found.

Syntax:

map_name.find( key );

Parameters: The multimap::find() accepts a single parameter:
• key: Key to search for
Return value: An iterator to the element with the given key. multimap::end() otherwise

Example of multimap::find() method

#include<iostream>
#include<map>

using namespace std;

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

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

    cout<< "value to key 'a': " << m.find('a')->second;
}

Output:

value to key 'a': 3
