difference in this 2 functions

Body

hello may I know the difference between cout.setf(cout.hex) and cout.setf(ios::hex) .....? they seem to get me the same output as I tried to format what im printing to hexadecimal. if im not wrong, the ios:: thing is because the function is from a class ios in the header file iostream, that is why a scope resolution operator is used to refer to it. am I right? or is there anything else I need to know?
