Task

What does a constructor do?

The editor already contains a starting point. Change it until every check passes — the Next task button unlocks when it does.

What you start with

#include <iostream>
using namespace std;

class Fee {
public:
    int monthly;

    Fee(int value) {
        monthly = value;
    }

    int forMonths(int months) {
        return monthly * months;
    }
};

int main() {
    Fee f(9000);
    cout << f.forMonths(2) << endl;
    return 0;
}
