Write data to c++ analytic structures?

Question

C++ / C#

There is a database file orders_class.txt

orderItemID;orderDate;deliveryDate;itemID;size;color;manufacturerID;price;customerID;salutation;dateOfBirth;state;creationDate

...

and there are such structures
There is such a code

#include <iostream>
#include <fstream>
#include <string>
#include <vector>
struct Customer
{
  int customerID;
  std::string salutation;
  std::string dateOfBirth;
  std::string state;
  std::string creationDate;
};
struct Item
{
  int itemID;
  std::string size;
  std::string color;
  int manufacturerID;
  double price;
};
struct Order
{
  int orderItemID;
  std::string orderDate;
  std::string deliveryDate;
  Customer *customer;
  Item *item;
};

int main()
{
  std::cout << "Hello world!" << std::endl;
  std::string str;
  std::ifstream file("C:\\Users\\User\\Desktop\\инт сис\\04\\orders_class.txt", std::ios::in);
  std::vector<Order>*vec = new std::vector<Order>();
  while (!file.eof())
  {
    getline(file, str);
    //std::cout << str << std::endl;
  };
  file.close();
  system("pause");
  return 0;
}

how to me to consider the data in a vector for the further processing?
