c++ question about operator overload.What's wrong exactly??

Question

The given code declares an Account class which has a balance and interest members.
The bank asks you to add a new functionality to merge two accounts together, resulting in a new account with the sum of the balances and interests of the given accounts.
Overload the + operator to allow adding two Account objects, adding the balances and interests.
The overloaded operator should return a new Account object, with the corresponding member values.

this is my code:

#include <iostream>
using namespace std;

class Account {
private:
int balance=0;
int interest=0;
public:
Account() {}
Account(int a): balance(a)
{
interest += balance/10;
}
int getTotal() {
return balance+interest;
}
//your code goes here
Account operator+(Account &obj){
Account res;
res.getTotal = this ->getTotal+obj.getTotal;
return res;

}

};

int main() {
int n1, n2;
cin >> n1 >> n2;
Account a(n1);
Account b(n2);
Account res = a+b;

cout << res.getTotal();
}

Answer 1

#include <iostream>
using namespace std;

class Account {
private:
int balance=0;
int interest=0;
public:
Account() {}
Account(int a): balance(a)
{
interest += balance/10;
}
int getTotal() {
return balance+interest;
}
//your code goes here
//
Account operator+(Account &obj){
Account res;
res.balance = this->balance+obj.balance + this->interest+obj.interest;
return res;
}
};

int main() {
int n1, n2;
cin >> n1 >> n2;
Account a(n1);
Account b(n2);
Account res = a+b;

cout << res.getTotal();
}

Answer 2

Nm, i did it thx a lot CarrieForle

Answer 3

#include <iostream>
using namespace std;

class Account {
private:
int balance=0;
int interest=0;
public:
Account() {}
Account(int a): balance(a)
{
interest += balance/10;
}
int getTotal() {
return balance+interest;
}
//your code goes here
Account operator+(Account &obj) {
Account res(this->balance+obj.balance);
return res;

}

};

int main() {
int n1, n2;
cin >> n1 >> n2;
Account a(n1);
Account b(n2);
Account res = a+b;

cout << res.getTotal();
}

Good Luck

Answer 4

getTotal() is a method, not a field (member variable), so it doesn't work. You should add the 2 fields separately.

Answer 5

How?
