Help me with class pls

[zerkas101]

I would instead of having to set name,lastname and phone in the code itself like to set it in the console and then print it, thanks.

#include "stdafx.h"
#include <string>
#include <iostream>
using namespace std;

class kontakt
{
public:
	void set_values(string, string, string);
	string returnname() { return name; }
	string returnlastname() { return lastname; }
	string returnphone() { return phone; }
private:
	string name, lastname, phone;

};

void kontakt::set_values(string x, string y, string z)
{
	name = x;
	lastname = y;
	phone = z;
}


int main()
{
	kontakt kontakt;
	kontakt.set_values("sven", "svensson", "070-0000000");
	cout << "Name: " << kontakt.returnname() << endl;
	cout << "Lastname: " << kontakt.returnlastname() << endl;
	cout << "Phonenumber: " << kontakt.returnphone() << endl;

	return 0;
}

    // print out information about the kontakt
    std::cout << "kontakt: " << my_kontakt.to_string() << '\n' ;

    // just as an example, to set values (the constructor subsumes kontakt::set_values)
    my_kontakt = { "mickey", "mouse", "123-456789" } ;
    std::cout << "updated kontakt: " << my_kontakt.to_string() << '\n' ;
