2 Classes Accessing Eachother

Alright I am writing a program that I need to give it the ability to have 2 seperate classes access eachother for example...
say I have class CUser and CChannel
they would look like this

Code:

---

class CUser
{
public:
 CChannel *ChannelList;
//functions here
}

---

and in a separate file I would have another class like this

Code:

---

class CChannel
{
public:
CUser *UserList;
//functions here
}

---

now if I try to include them to eachother with an ifndef in it so they do not go into an infinate loop it still doesnt declare them properly. Is there a way that I can get my classes to access eachother like this. Please help me out. and my main function by the way would pass the reference to each class

put prototypes of the other class above the class that access another (especially if it's in a different file)

ex:

Code:

---

class CChannel;
class CUser
{
public:
 CChannel *ChannelList;
//functions here
}

---

I think I might have just found a way guys...nevermind
