Counting the frequency of words in a string.

[abdalimran]

I've written a code on counting the frequency of words in a string which is given below.

#include <iostream>
#include <string>
#include <map>

using namespace std;

int main()
{
    map<string, int> m;
    string str;

    while(cin>>str)
    {
        if(str == "end") break;
        m[str]++;

        cout<<str<<" frequency = "<<m[str]<<endl;
    }

    return 0;
}

It gives me output like this- http://ctrlv.in/422823

But I want only the number of maximum frequency of a word as output...not the frequency that counts in every iteration.

I want the output to be like the following-

i frequency = 4
me frequency = 1
we frequency = 3
you frequency = 2
can  frequency = 1

Now how to write that code?
