What output will be produced when the following lines are executed
(assuming the lines are embedded in a complete and correct program
with the proper include directives)?
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;
