STL Map

I am trying to get this map to to store cutomer names and referenced by a id number. I cannot figure out why i am getting 18 errors. I am confused. here is the code, thanks in advance for any help.

Code:

---

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

using namespace std;
 

void main (void)
{

        typedef map<int, string, less<int>> C;

        C customer;
               
        customer.insert(C::value_type(5, "Dave"));
        customer.insert(C::value_type(45, "Jon"));
        cout<<"PIN Number"<<'\t'<<"Name"<<endl;

        C::const_iterator i;

        for(i=customer.begin(); i!=customer.end(); ++i)
                cout<<i->first<<'\t'<<'\t'
                        <<i->second<<'\n';

       
}

Thanks to the wonderful world of C++ parsing, in typedef map<int, string, less<int>> C; the >> is a single token. Put a space between the greater than characters and everything should be fine: typedef map<int, string, less<int> > C;. And make sure you use int main(void). Not only is it the correct way, but it is one character less than void main(void).
