Bagaimanakah saya Boleh Menggunakan printf dengan std::string dalam C ?

#include <iostream>
#include <string>
#include <stdio.h>

int main()
{
    using namespace std;

    string myString = "Press ENTER to quit program!";
    cout << "Come up and C++ me some time." << endl;
    printf("Follow this command: %s", myString.c_str());
    cin.get();

    return 0;
}

Come up and C++ me some time.
Follow this command: Press ENTER to quit program!

#include <iostream>
#include <string>
#include <sstream>

int main()
{
    using namespace std;

    string myString = "Press ENTER to quit program!";
    cout << "Come up and C++ me some time." << endl;
    ostringstream oss;
    oss << "Follow this command: " << myString;
    printf("%s", oss.str().c_str());
    cin.get();

    return 0;
}
