What output is produced by the following code, assuming these lines of code are embedded in a correct program?

```
cout << "*" << setw(5) << 123 << "*"
<< 123 << "*" << endl;
cout.setf(ios::showpos);
cout << "*" << setw(5) << 123 << "*"
<< 123 << "*" << endl;
cout.unsetf(ios::showpos):
cout.setf(ios::left);
cout << "*" << setw(5) << 123 << "*"
<< setw(5) << 123 << "*" << endl;
```

Using g++, output is the following, after embedding the code in a correct program:
123*123*
+123*+123*
*123 *
