Hello,
I am studying c++, and the book I'm reading always says to use nullptr instead of null, but this error happens:

error: 'nullptr' was not declared in this scope

I'm missing some #include?

I'm including this:

Code:
#include <iostream>
#include <cstring>
#include <stack>
#include <cstdlib>

using namespace std;

Please learn the difference between an Compiler and an IDE; Code::Blocks is an IDE.
Please read the rules http://forums.codeblocks.org/index.php/topic,9996.0.html
Please read how to ask a smart question http://catb.org/~esr/faqs/smart-questions.html#forum

Learn to ask programming questions in a site that does this like http://cboard.cprogramming.com/

Turn on Full Compiler logging to help others help you; note this requires you to post information from the log!!

Unless you use something more recent than gcc 4.6 in std=c++0x mode, you must implement nullptr yourself as a template class (or in any other way, constant or macro).
