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>
#include <vector>
using namespace std;

int main() {
    vector<int> fees{9000, 11667, 15000};
    cout << fees[0] << endl;
    fees[1] = 12000;
    cout << fees[1] << endl;
    return 0;
}
