Hi
I am a beginner and currently I am working on a program.
I have a main class called 'FenPrincipale' of daughter classes 'FenCene' and 'FenCenep'.

1. C++ 11 Nullptr
2. Nullptr Was Not Declared In This Scope Dev C++
3. ‘nullptr’ Was Not Declared In This Scope C++
4. C++ Nullptr Check
5. C++ Include For Nullptr

C++ 11 Nullptr

My IDE sends me the following error at fencen.h and fencenep.h

Nov 03, 2011 C11 adds a null pointer constant called nullptr.The use of nullptr should be preferred over 0 or NULL.GCC just added a warning for the use of 0 as a pointer, so they are strongly encouraging you to use nullptr. Nullptr (since C11) Explanation. The keyword nullptr denotes the pointer literal. It is a prvalue of type std::nullptrt. There exist implicit conversions from nullptr to null pointer value of any pointer type and any pointer to member type. The keyword nullptr denotes the pointer literal. It is a prvalue of type std::nullptrt. There exist implicit conversions from nullptr to null pointer value of any pointer type and any pointer to member type. Similar conversions exist for any null pointer constant, which includes values of type std::nullptrt as well as the macro NULL. I am running Eclipse Helios and I have g-4.6 installed. Hope I am not wrong that g4.6 implements C 11 features. I have created a C project which uses the nullptr and auto keywords.

'nullptr was not declared in the scope'
'identify 'nullptr' is a keyword in C ++ [-wc ++ 0x-compat]

The notification is the same in the headers of the two classes.

Here is the code of fencene.h

Here is the code of fencenep.h

Nullptr Was Not Declared In This Scope Dev C++

/nch-software-auto-tune.html. Here is the code of fenprincipale.h

‘nullptr’ Was Not Declared In This Scope C++

What can I do to fix the problem?

C++ Nullptr Check

Thank you in advance..
