Exception thrown - c++

Question

I am working on a project and I'm a beginner. The project involves a person, adult, kid and bogie class. In bogie class I have initialsed pointer of type person named adult as adult = new Adult [adultcount], where adultcount is the number of adults user wants to add.
When I add only one adult in input, it works fine, it takes the input and assigns it in while assigning values in for loop.
But when I add more than one, it stops working and says exception throw at line Adults[i].setdata().
#include<iostream>
#include<string>
using namespace std;
class Person {
public:

int Age;
string Gender;
public:

}
Person(string Name, int Age, string Gender)
{
this->Name = Name;
this->Age = Age;
this->Gender = Gender;
}
virtual void setdata()
{
string name, gender;
int age;
cin.ignore();
cout << " enter Name :";
getline(cin, name, '\n');
this->Name = name;
cout << endl;
cout << " Enter gender ";
getline(cin, gender, '\n');
this->Gender = gender;
cout << endl;
cout << " Enter age ";
cin >> age;
Age = age;

Answer 1

I believe you need to change Adults from Person * to Adult *.
When the program tries to access Adults[1] at
for (int i = 0; i < adultcount; i++)
{
Adults[i].setdata();
}
It jumps ahead sizeof(Person) in the array, while the objects in the array are sizeof(Adult), which leads to the exception you're seeing.

Answer 2

so I found the answer the appropriate method to to it was declaring pointers named adult and kid in the members as
Person ** Adults;
Person **kids
and then
adults = new Person * [adultcount];
for (int i = 0; i < adultcount; i++)
{
adults[i] = new Adult;
adults[i]->setdata();
}
