Facing little issue,help

Question

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

//complete the function with one default argument
void printOrder(string order="Blacktea",string friendOrder ){
cout<<order<<friendOrder;
}
int main() {
//getting coffee type
string friendOrder,order ;
cin >> friendOrder;
cout<<friendOrder<<endl;
printOrder(friendOrder);
printOrder(order);
return 0;
}

Answer 1

Arguments with default values must come last in the argument list, i.e. there may be no argument without a default value after one with a default value. Simply switching the arguments should do the trick.

Answer 2

void printOrder(string order,string friendOrder="Blacktea"){
cout<<order<<friendOrder;
}

Didn't understand this question, but code works for me. I've set the value "Blacktea" to the second default argument.

void printOrder(string order,string friendOrder="Blacktea"){
cout<<order<<friendOrder;
}
