Associating two objects (each with a class) in an array using pointers

Question

The goal of my program is to allow the user to enter up to 100 names for people and 100 names for cars. Then the user can "register" a car to as many people as s/he wishes using pointers. I know I need a person class and a car class and I need to use two arrays of size 100 for each. But I am completely lost on how to set anything else up. I have done a lot of researching to try and figure something out. I would be extremely appreciative if anyone could give me some basic example code for how something like this could be done.

I don't have much code:

class Person{
public:
    person();
    Car* in_car;
};

class Car{
public:
    Car();
};

int main()
{
    Car cars[101];
    Person people[101];
}

start cr eating the objects and use data structures for associations — Balu

Could you be more specific as to how to use data structures for association? — borchr

You could add a vector of car pointers to the People class.

class People{
...

private:

vector<Car*> _pointer;
};

The code I'm creating now will be used in part of a larger project where it will be necessary to have used an array

It is probably better to use a std::set for tracking the association, this would avoid duplicate registration.

No problem you can substitute vector for array. stackoverflow.com/questions/8399001/…
