Exercise 41.2: Default arguments

Question

So far all I am getting is this:

Input
Sandwich
Your Output
Sandwich
Expected Output
Black tea
Sandwich

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

//complete the function with one default argument
string printOrder(string x = "Black tea") {
return x;
}

int main() {
//getting coffee type
string friendOrder;
cin >> friendOrder;

cout << printOrder(friendOrder) << endl;

return 0;
}

How do you change the rightmost arguments, while still allowing the leftmost arguments to stay as defaults?

Thanks!

Answer 1

Default Arguments in C++ should be the rightmost, if you want other arguments then it should be on left side. In your case, add another argument while rightmost being default argument and then print both the strings in function or concat them and return.
