23.6.7.Insert key-value pairs into the map using value_type

#include <map>

#include <iostream>



using namespace std;



typedef map <int, string> MAP_INT_STRING;

typedef multimap <int, string> MMAP_INT_STRING;



int main ()

{

    MAP_INT_STRING mapIntToString;



    // Insert key-value pairs into the map using value_type

    mapIntToString.insert (MAP_INT_STRING::value_type (3, "Three"));



    cout << "The map contains " << mapIntToString.size ();

    cout << " key-value pairs. " << endl;

    cout << "The elements in the map are: " << endl;



    return 0;
