Re^3: question regarding "v" flag of printf
in thread question regarding "v" flag of printf
As it was described, "This flag tells Perl to interpret the supplied string as a vector of integers, one for each character in the string. Perl applies the format to each integer in turn, then joins the resulting strings with a separator (a dot . by default)"
and it's actually as rjt said,"Perl interprets each character in the string as its index in your character set."
it's "index",not the number in the string.
