Output:

// This does not work ...  WTF?
  
   using namespace std;
 
   int i = 10;
 
   cout << i << endl;
 
   cout.setf( ios_base::hex | ios_base::uppercase, ios_base::dec );
   cout << i << endl;
 
   cout.setf( ios_base::dec );
   cout << i << endl;
 
   cout.setf( ios_base::hex, ios_base::dec | ios_base::uppercase );
   cout << i << endl;
 
Output:
10
10
10
10

*EDIT* And, in the "working" example, why on the 3rd cout does the hex flag not nead to be unset.<br />
In fact doing so causes it to fail
