strf

Explanation Replaces %n that appears in the format string with the string specified by the subsequent argument str_n.
%n specifies the next argument of the format string as %1 and the next as %2.

If there are fewer arguments than %n, it is assumed that an empty string was specified and %n is deleted.

If you want to include the character "%" in the format string, specify it in duplicate like "%%".
However, if % is not followed by a number,% is output as is.
