How to store multiple inputs in C++ by space

I am new to C++ and I want the user to input a set of data followed by spaces like this:

Mark 23 California, USA
Susan 22 Tokyo, Japan
Anna 21 New Mexico, USA

I am not sure how to gather all of these separate information. I want to categorize them by name, age, location so I can access them later on by using (age[0]. age[1], etc)

So far, this is what I have

std::vector<std::string> name, age, location:
std::cout << "Hello, what is your Name Age Location? (separate by space) ";
std::string a, b, c;
std::cin >> a;
std::cin >> b;
std::cin >> c;
a.push_back(name);
b.push_back(age);
c.push_back(location);

std::cout << "How many people would you like to store their data? ";
int n;
std::cin >> n;

for (int a=0;a<n;a++){
    std::cout << "Please enter the Name Age Location for Person #" << n << ": ";
    std::string x, y, z;
    std::cin >> x;
    std::cin >> y;
    std::cin >> z; //this part always gets me because the location is separated by a space and always gets cut off
    x.push_back(name);
    y.push_back(age);
    z.push_back(location);
}

I want to know how to be able to store the rest of the information after the 2nd white space until the end of the line. Thank you!!

You read the name and age values as you're doing, but then use std::getline to get the rest of the line, i.e. the location.

std::cin >> name;
std::cin >> age;
std::getline(std::cin, location); // voila!

std::cin will break the line in general after a space, use std::getline() instead:

char buffer[256];
std::getline(buffer, size(buffer));
