Perl Programmers what does this mean

I am trying to figure out what this code does

Code: Select all

my $junk   = "\x41"  x 200;

I understand that my has to do with scope \x41 is a hex value but what is x 200 suppose to do

x is declared no where in the code so I can't imagine if its suppose to do anything. Is it a way to concatenate on to the \x41

this is from exploit code so is it a bug perhaps


Any ideas cheers

Never mind just figured it out "replicate the string on the left the number of times on the right"

Edit * Equivalent in python

Code: Select all

You could have found out using a simple

Code: Select all

print $junk

statement.

sounds like math

It is. In formal language theory, a string is a sequence of symbols from an alphabet. The concatenation of strings x and y, written xy (like multiplication) is the string obtained by appending y to the end of x. A string concatenated with itself many times is written x^k (repeated multiplication of x, that makes sense).
