TestNote: Despite the uppercase, David is printed as David and not DAVID. This is because uppercase only affects generated output- e.g. numbers printed in hexadecimal. So the hex output 4d2 is 4D2 when uppercase is in operation.

Also, most of these manipulators actually set a bit in a flag and it is possible to set this directly with
cout.setf()and clear it with
cout.unsetf()
