expected unqualified-id before '>>' token when using Strings

[Phroton]

I was just a begginer, so I want to know what unqualified-id is.
I was using a string with cin functions. I am confused because I don't know what unqualified ids and when to use them.

Sorry for my bad english and long code.

#include <iostream>
#include <string>
using namespace std;
struct address{
    string country;
    string province;
    string city;
    int zipcode;
    string residence;
    string street;
};
struct person{
    string name;
    string contact_no;
    float height;
    int age;
    address addr;
};
int main()
{
    person human;
    //structure: Person
    cout << "Name: ";
    std::string >> human.name;
    std::getline(cin, human.name);
    cout << "Contact# :";
    std::string >> human.contact_no;
    std::getline(cin, human.contact_no);
    cout << "Height: ";
    cin >> human.height;
    cout << "Age: ";
    cin >> human.age;
    //structure: Address
    cout << "Address" << endl;
    cout << "Country: ";
    std::string >> human.addr.country;
    std::getline(cin, human.addr.country);
    cout << "Province: ";
    std::string >> human.addr.province;
    std::getline(cin, human.addr.province);
    cout << "City: ";
    std::string >> human.addr.city;
    std::getline(cin, human.addr.city);
    cout << "Zipcode: ";
    cin >> human.addr.zipcode;
    cout << "Residence: ";
    std::string >> human.addr.residence;
    std::getline(cin, human.addr.residence);
    cout << "Street: ";
    std::string >> human.addr.street
    std::getline(cin, human.addr.street);

    cout << "Here's your input: ";
    cout << "Name: " << human.name << endl << "Contact: " << endl << human.contact_no << endl << "Height: " << human.height << endl << "Age: " << human.age << endl;
    cout << "Address:" << endl;
    cout << "Country: " << human.addr.country << "Province: " << human.addr.province << "City: " << human.addr.city << endl << "Zipcode: " << human.addr.zipcode << endl << "Residence: " << human.addr.residence << endl << "Street: " << human.addr.street << endl;
    cout << "Sending Info to Phroton/Detron";

    return 0;
}

std::string >> human.name;
This makes no sense and I can see no reason why it exists. What are you trying to do here?
