What will be the output of the following C++ code?

#include <iostream>
#include <map>
using namespace std;
int main ()
{
    multimap<char, int> mymultimap;
    mymultimap.insert(make_pair('y', 202));
    mymultimap.insert(make_pair('y', 252));
    pair<char, int> highest = *mymultimap.rbegin();
    multimap<char, int> :: iterator it = mymultimap.begin();
    do 
    {
        cout << (*it).first << " => " << (*it).second << '\n';
    } while ( mymultimap.value_comp()(*it++, highest) );
    return 0;
}
