How to declare a pointer to an user defined object with constructor?

Question

I have two classes: Game and inputs. Game class has a constructor that takes no variables, while inputs class takes pointer to Game object as an argument (or at least is supposed to).

In main I create two instances of thes objects:

Game main_game; 
inputs main_inputs(&main_game);

And that is the troublesome part of inputs.h:

class inputs{
public:
   Game *wsk;
   inputs(Game *);
};

The compiler gives me two errors in inputs.h:

1) 'Game' does not name a type 2) expected ')' before '*' token

What am I doing wrong, trying to pass adress of Game object to inputs constructor?

You have to #include the header with the definition of Game or provide a forward-declaration and do that in the .cpp file. — LogicStuff

It seems you forgot to forward declare Game:

class Game;

class inputs{
public:
   Game *wsk;
   inputs(Game *);
};

What do you not understand about "'Game' does not name a type"?
