C++ Program to Illustrate Usage of Map Container

#include <iostream>
#include <map>
 
int main()  
{
    std::map <int, std::string> Country;
    std::map <int, std::string>::const_iterator i;
    Country.insert(std::pair <int, std::string>(1, "USA"));
    Country.insert(std::pair <int, std::string>(7, "Russia"));
    Country.insert(std::pair <int, std::string>(33, "France"));
    Country.insert(std::pair <int, std::string>(39, "Italy"));
    Country.insert(std::pair <int, std::string>(49, "Germany"));
    Country.insert(std::pair <int, std::string>(61, "Australia"));
 
    std::cout << "ISD\tCountry " << std::endl;
    std::cout << "---\t--------" << std::endl;
    for (i = Country.begin(); i != Country.end(); i++)
    {
        std::cout << (*i).first << "\t" << (*i).second
                  << std::endl;
    }
    return 0;
}

Output:
ISD     Country
---     --------
1       USA
7       Russia
33      France
39      Italy
49      Germany
61      Australia
