Error using nullptr

(1/1)

gusth:
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;

--- End code ---

Please learn the difference between an Compiler and an IDE; Code::Blocks is an IDE.

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).
