When is a default argument used?

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 <string>
using namespace std;

string greet(string name, string title = "student") {
    return "Hi " + title + " " + name;
}

int main() {
    cout << greet("Awais") << endl;
    cout << greet("Sara", "monitor") << endl;
    return 0;
}
