As the problem says, the value of the palindrome may exceed your system's defined integer size in C/C++.
Good challenge, and I've been working on it for a while now. I can't get a function to determine if a number is a palindrome, but I'll work more on it later.

NAME
Regexp::Common::lingua -- provide regexes for language related stuff. SYNOPSIS
use Regexp::Common qw /lingua/; while (<>) { /^$RE{lingua}{palindrome}$/ and print "is a palindrome "; } DESCRIPTION
Please consult the manual of Regexp::Common for a general description of the works of this interface. Do not use this module directly, but load it via Regexp::Common. $RE{lingua}{palindrome} Returns a pattern that recognizes a palindrome, a string that is the same if you reverse it. By default, it only matches strings consisting of letters, but this can be changed using the "{-chars}" option. This option takes a character class (default is "[A-Za-z]") as argument. If "{-keep}" is used, only $1 will be set, and set to the entire match. This pattern requires at least perl 5.6.0. SEE ALSO
