It's been a long time since I've done C++ and I'm running into some trouble with classes referencing each other.

Right now I have something like:

a.h

class a
{
  public:
    a();
    bool skeletonfunc(b temp);
};

b.h

class b
{
  public:
    b();
    bool skeletonfunc(a temp);
};

Since each one needs a reference to the other, I've found I can't do a #include of each other at the top or I end up in a weird loop of sorts with the includes.

So how can I make it so that a can use b and vice versa without making a cyclical #include problem?

thanks!
