I am relatively new to C++. However, I am tutoring myself on the differences
of int expressions and bool expressions. The gnu gxx comipler doesn't
recognize 'ios_base::boolalpha' argument in the statement
'cout.setf(ios_base::boolalpha)'. I have since learned that the 'ios_base'
should be replaced with 'ios' in the current implementation of g++. With
what argument do I replace 'boolalpha'? The compiler gives the error that
'boolalpha' is not a member of type 'ios'. obviously, being somewhat new I
am at a loss. Please help and thanks in advance!

    cout << (x < 3) << "\n";
    cout << "The expression x > 3 has the value ";
    cout << (x > 3) << "\n";
    cout.setf(ios_base::boolalpha);
    cout << "The expression x < 3 has the value ";
    cout << (x < 3) << "\n";
    cout << "The expression x > 3 has the value ";
    cout << (x > 3) << "\n";
 return 0;
