Use functions to reuse code

Read first Task 28

Small functions are easier to test and change.

Task

Why split code into small functions?

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;

int monthly_after_discount(int fee, int percent) {
    return fee - (fee * percent) / 100;
}

int main() {
    cout << monthly_after_discount(9000, 10) << endl;
    cout << monthly_after_discount(11667, 10) << endl;
    return 0;
}
