C++ Operator Overloading always false - c++

Question

So I was able to fix it, however, the operator doesn't seem to be comparing them both since I always get false. There seems to be an error with the pLoan where it is not comparing both of them.
My code is
#include <string>
#include <iostream>
#include <sstream>
using namespace std;
//Vehicle Class
class Vehicle {
public:
Vehicle();
void setPrice(double a);
void setMpg(int a);
double getPrice() const;
int getMpg() const;
void printVehicle() const;
Vehicle(double price, int mpg);
private:
double price;
int mpg;
};
//Loan Class
class Loan {
public:
void setBank(string a);
void setLoan(double a);
string getBank() const;
double getLoan() const;
void printLoan() const;
Loan(string bank = "", double loan = 0);
private:
string bank;
double loan;
};
//Car Class
class Car : public Vehicle {
public:
Car(double price = 0, int mpg = 0, string bank = "", double loan = 0, string name = "", int element = 0);
void setName(string a);
void setLoan(string b, double l, int element);
string getName() const;
void printFull() const;
void setNbrOfLoans(int a);
int getNbrOfLoans() const;
Loan* getpLoan() const;
~Car();
private:
string name;
Loan* pLoan;
int nbrOfLoans;
};
bool operator==(const Car &car1, const Car &car2) {
Loan* pLoan1 = car1.getpLoan();
Loan* pLoan2 = car2.getpLoan();
return ((car1.getPrice() == car2.getPrice()) && (car1.getMpg() == car2.getMpg()) && (car1.getName() == car2.getName())
&& (car1.getNbrOfLoans() == car2.getNbrOfLoans()) &&
(pLoan1[0].getBank() == pLoan2[0].getBank()) && (pLoan1[0].getLoan() == pLoan2[0].getLoan()));
}
//Main
int main() {
Car car1(24800, 22, "Citi", 21600, "Mustang", 1);
Car* pCar1 = &car1;
pCar1->setLoan("Citi", 21600, 0);
pCar1->printFull();
pCar1->setNbrOfLoans(1);
Car car2;
Car* pCar2 = &car2;
cout << boolalpha;
cout << "Enter the price of the car: ";
double price;
cin >> price;
pCar2->setPrice(price);
cout << "Enter the mpg: ";
int mpg;
cin >> mpg;
pCar2->setMpg(mpg);
cout << "Enter the name of the car: ";
string name;
cin >> name;
pCar2->setName(name);
string bank;
double loan;
int index;
cout << "Enter the amount of loans you obtained: ";
cin >> index;
pCar2->setNbrOfLoans(index);
for (int i = 0; i < index; i++)
{
cout << "Enter the name of bank " << i + 1 << ": ";
cin >> bank;
cout << "Enter the amount of loan " << i + 1 << ": ";
cin >> loan;
pCar2->setLoan(bank, loan, i);
}
if (pCar1 == pCar2)
cout << "Cars are the same. ";
else
cout << "Cars are not the same. ";
cout << endl;
pCar2->printFull();
return 0;
}

cout << endl;

}

}
Output:
IS always cars are not the same even when they are

Answer 1

Your main code is not calling your operator ==:
if (pCar1 == pCar2)
cout << "Cars are the same. ";
else
cout << "Cars are not the same. ";
here you're comparing the two pointers. To compare the two pointed-to objects you need
if (*pCar1 == *pCar2) ...

Answer 2

One more error:
pCar1->setLoan("Citi", 21600, 0);
pCar1->printFull();
pCar1->setNbrOfLoans(1);
setNbrOfLoans must be located before setLoan:
pCar1->setNbrOfLoans(1);
pCar1->setLoan("Citi", 21600, 0);
pCar1->printFull();
