I know (of course)... Try this:

printf("%|26s","Center me");

Why? To understand this, you need to know more about formatting strings
(e.g. usage of format strings like "%10d" etc.). See, "|" is the formatting
flag option which tells that the appropriate argument will be centered in
the reserved space. 26 is the width of the reserved space in this case.
So, look the following:

printf("%s","Center me");    

prints just "Center me", because "%s" means "print the appropriate arg
as a string".

printf("%26s","Center me");

reserves a 26-character wide space, and prints the appropriate arg
("Center me") into this space, right alligned. Note that 26 is the
width of the screen if you use medium font size.

I hope that you now can guess the meaning of

printf("%|26s","Center me");
