Task

Why use a map?

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 <map>
#include <string>
using namespace std;

int main() {
    map<string, int> fees;
    fees["Web Design"] = 9000;
    fees["Python"] = 11667;
    cout << fees["Python"] << endl;
    return 0;
}
