int main() {

string str;

{

string str = "hello world";

cout << stringFunc1(str) << endl;

cout << str << endl;

}

if (str == "hello world!")

cout << "awesome sauce";

else

cout << "bummer dude";

}

string stringFunc1(string &str)

{

str = str + "!";

return "goodbye world";

}

What would the output of this code be when completed?
