   cout << b << endl;   // Good
   cout.clear( ios::badbit );
   b = cout.bad( );
   // cout.clear( );
   cout << b << endl;   // Is bad, good
   b = cout.fail( );
   cout << b << endl;   // Not failed
   cout.setstate( ios::failbit );
   b = cout.fail( );
   cout.clear( );
   cout << b << endl;   // Is failed, good
