[Practice 41.2] Why does my code output ‘1’?

Question

Hello, I’m currently stuck on Practice 41.2 but I’m not sure what’s wrong with my code. It keeps outputting 1 for an odd reason, despite all of the data types being ‘string’. Here’s my code:

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

//complete the function with one default argument

void printOrder (string a, string b="Black_tea") {

}

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

printOrder(friendOrder);

cout << printOrder;
return 0;

I appreciate any help :)

Answer 1

Plaush You are outputting function name which doesn't make sense. The output may be any undefined value .

Answer 2

Nvm, I solved it. Turns out, I was being an idiot. Solved it by placing cout ‘inside’ the function’s curly brackets. Thanks for the help! :) p

Answer 3

Hima Ahh, I see. I’ll assign it to something :)

Answer 4

Plaush The function is of type void so you can not assign it to anything .

Answer 5

Hima Hmm, you’re right. It gives me an error

Answer 6

void printOrder (string a, string b="Black_tea") {
cout << "Black tea";
}
