They pull a value into the string...ex: %d would turn into whatever the first variable of that type in the arguments list.
%d is integer
%s is string
%c is a character
there are more but I dont have time to look them all up currently
hope that helps you.

It''s all in the documentation for printf and its format string. They are typed placeholders for the subsequent arguments.
