Default arguments

Question

I hade some problem to solve this, then I figure out right answer. Maybe it helps someone else :)
Your usual order at your favorite cafe is black tea, which the waiter brings you by default. Today, however, you are with your friend and it is his first time there. Obtain your friend's order in one word as input, and place the order for both of you. Complete the function so that it will output "Black tea" by default (without an argument) and then your friend's order as an argument.
Sample Input
Americano
Sample Output
Black tea
Americano
Here is my code:
#include <iostream>
#include <string>
using namespace std;
//complete the function with one default argument
string printOrder(string friendOrder, string myOrder="Black tea") {
return myOrder + "\n" + friendOrder;
}
int main() {
//getting coffee type
string friendOrder;
cin >> friendOrder;
cout << printOrder(friendOrder);
return 0;
}

Answer 1

All pass try this code
#include <iostream>
#include <string>
using namespace std;
//complete the function with one default argument
void printOrder(string Order="Black tea"){
cout<<Order<<endl;
}
int main() {
//getting coffee type
string friendOrder;
cin >> friendOrder;
printOrder();
cout<<friendOrder;
return 0;
}

Answer 2

#include <iostream>
#include <string>
using namespace std;
//complete the function with one default argument
string printOrder(string friendOrder, string myOrder="Black tea") {
return myOrder + "\n" + friendOrder;
}
int main() {
//getting coffee type
string friendOrder;
cin >> friendOrder;
cout << printOrder(friendOrder);
return 0;
}
Good Luck

Sara N i didn't understood your question as per my understanding u need to make two methods one for default value another one for parameter passing.
