How to allow setw apply to all the following stdout?

Question

Should be a trivial question, but found that setw only apply to its immediate following output, and not sure how to allow it apply to all the following output.

For example, for the following line of code

cout<<setw(3)<<setfill('0')<<8<<" "<<9<<endl;

or

cout.width(3);
cout.fill('0');
cout<<8<<" "<<9<<endl;

I want the output to be 008 009 instead of 008 9

setw isn't sticky, so you have to say it every time:

cout << setfill('0') << setw(3) << 8 << " "
     << setw(3) << 9 << endl;
