Program runs through compiler but not giving answers(C++ Classes) - c++

Question

I'm new to C++ OOP and I find difficulties in implementing the following task:
The program is about taking information from a file, storing it in vector pointers and then printing it, but it gives proccess failure.
Basically doesn't call the second constructor in class Car and I don't seem to find a way to fix this issue.
Would like to get some tips.
#include <iostream>
#include <fstream>
#include <vector>
using namespace std;
class Person{
protected:
string name;
int age;
public:
Person(string n, int a) {
name = n;
age = a;
cout << "Constructor called" << endl;
}
void IncAge(){
age++;
}
string get_name() {
return name;
}
int get_age() {
return age;
}
};
class Car{
public:
string brand;
Person* owner;
Person* driver;
Car(string b, Person* o, Person* d){
brand = b;
owner = o;
driver = d;
cout << "Constructor 2 called" << endl;
}
string get_brand(){ return brand; }
void get_owner(){ cout << owner; }
void get_driver(){ cout << driver; }
};
void printall(vector<Car*> car){
for(int i =0; i < car.size(); i++){
cout << car[i]->get_brand();
}
}
int main() {
vector<Person*> people;
vector<Car*> cars;
ifstream openFile;
string filename = "input.txt";
openFile.open(filename.c_str());
if(openFile.fail()){
cout << "Failed opening targeted file!" << endl;
return 1;
}
else{
int n;
int read_age;
string read_name, read_car, read_owner,read_driver;
openFile >> n;
for(unsigned int i = 0; i < n; i++){
openFile >> read_name;
openFile >> read_age;
people[i] = new Person(read_name, read_age);
}
openFile >> n;
for(unsigned int i = 0; i < n; i++){
openFile >> read_car;
openFile >> read_owner;
openFile >> read_driver;
unsigned int j = 0;
unsigned int k = 0;
for(; j < people.size(); j++){
if(read_owner == people[j]->get_name()) break;
}
for(; k < people.size(); k++){
if(read_driver == people[k]->get_name()) break;
}
cars[i] = new Car(read_car, people[j], people[k]);
}
openFile.close();
for(unsigned int i = 0; i < people.size(); i++) {
people[i]->IncAge();
}
printall(cars);
}
return 0;
}

Answer 1

I am also learning c++, I want to comment instead of writing this as an answner, but I can't do it now.
people[i] = new Person(read_name, read_age);
use push_back() function to add person to vector
I don't think [index] will properly increase the size of vector and reallocate memory for new element
