cpp multidimensional vector

Question

I want to store theses string vectors as a 4 dimensional vector. It has been three days that I am searching and I can not decide wether use multidimensional vector,boost multi array ,array of struct ,... I am so new to cpp and they are so confusing.

vector < string >ID;
vector < string > firstName;
vector < string > lastName;
vector < string > address;
vector<vector<vector<vector<string> >>> person ;

what should I do for populating person ?

Answer 1

In your case, there is no point in creating multidimensional array. I'd rather try:

class Person
{
public:
    string Id;
    string firstName;
    string lastName;
    string address;
};

(...)

vector<Person> People;

// Adding
Person p;
p.Id = "1234";
People.push_back(p);

// Count
std::cout << "Currently you have " << People.size() << " people in the database";

// Access
Person p1 = People[0];

Edit: In response to comments

It's quite tough to answer the question without some specifics about your problem. From what little I know about it, I'd probably go into multi-class version:

class Id
{
public:
    int Value;
    std::vector<FirstName> Names;
}

class FirstName
{
public:
    string Value;
    std::vector<SecondName> SecondNames;
}

class SecondName
{
public:
    string Value;
    std::vector<Address> Addresses;
}

class Address
{
public:
    string Value;
}
