error: ‘Class’ was not declared in this scope

Question

I would like to ask, how can I define class inside another one. In the code below. I try to define it in the way #define "CCompField.h" ,but it doesn't work. :(. I think that it is very common programming problem, probably it was 100000 times solved on the internet, but I don't know how to find it. Thanks for help. ``` #ifndef CNEWGAME_H #define CNEWGAME_H class CNewGame{ public: CNewGame(); ~CNewGame(); void BeginnerGame(); void IntermediateGame(); void AdviceGame(); void HowToPlay(); void NetGame( int mode ); int MoveInMenu(); protected: void Intro(); void Animation (); void Menu(int); int MoveInNetMenu(); void NetMenu(int); void HeadOfGame(); template <class T> void BodyOfGame(CCompField & b, T & a); void FooterOfGame(); }; #endif ``` It makes following errors. ``` In file included from src/CNewGame.cpp:12:0: src/CNewGame.h:37:36: error: ‘CCompField’ was not declared in this scope src/CNewGame.h:37:45: error: ‘b’ was not declared in this scope src/CNewGame.h:37:50: error: expected…

Accepted Answer

Instead of `#define "CCompField.h"` you need to include it:

```
#include "CCompField.h"
```

You also have an extra pair of

```
#ifndef CNEWGAME_H
#define CNEWGAME_H  
```

but only one closing `#endif`. You don't need the second pair of `#ifndef`/`#define`
