I've written a code in which I'm passing class as a parameter in fucntion the copy constructor for the class is written too in the body of the code

#include <iostream>
#include <string>
using namespace std;

class Move
{
private:
    int* age;
public:
    Move(int d);
    Move(const Move& source);
    ~Move();
    int get_value() { return *age; }
};

Move::Move(int d)
{
    age = new int;
    *age = d;
}
Move::Move(const Move& source)
{
    age = new int;
    *age = *source.age;
}

Move::~Move()
{
    delete age;
}

void display_element(Move P)
{
    cout << "the age of p is: " << P.get_value()<<endl;
}

int main()
{
    Move waleed(5);
    display_element(waleed);
    Move ahmed(waleed);
    display_element(ahmed);
    return 0;
}

I'm wondering where is the object of the (*age) member in the copy constructor body? every member should have a specific object in copy constructor I'm copying the age of waleed in newly *age member that will be passed later in the function so before passing it to the function where is the object decleration of this member

What I have tried:

I've tried to debug and see locals to see what's going behind I see a pointer variable called this is being created when the constructor is called maybe there is a relation between it and my question?
