我想将这些字符串向量存储为4维向量。我已经搜索了三天，我无法决定是否使用多维向量，增强多数组，结构数组，...
我对cpp还是那么陌生，他们是如此混乱。

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

我该怎么办？

最佳答案

在您的情况下，创建多维数组毫无意义。我宁愿尝试：

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];

没有有关您的问题的详细信息，很难回答这个问题。据我所知，我可能会进入多类版本：

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;
}
