C++ people... a little help with display please

I want to output an 8 digit hex value, say 00000104. When I use cout it gets rid of leading 0's and prints "104". How can I have output that shows leading 0's as well?

cout << setiosflags(ios_base::right) << setw(8) << setfill('0') << yourthing;

oh yeah remember to include <iomanip>

Ok, what if I have other hex and string values being output after that. Can I put them in the same cout statement or do I need another one? I guess, what is the scope of setiosflags, setw, and setfill?

i'm not totally sure without experimenting with it. i think it persists for at least the whole statement.

Alright, i'll tinker with it.

if you do it this way...
cout << setiosflags(ios_base::right) << setw(8) << setfill('0') << yourthing;
its set just for that line.



if you do it this way...
cout.setiosflags(ios_base::right);
its set permanently until you unset it.

I know, but people usually don't see things there.
