Using multiple files

I have a question about a problem that I've been having that gets in the way of development. Say I have file a.h, and file b.h.

File b.h contains:

Code:

---

class x {
 public:
  y obj_y;
};

---

and file a.h contains:

Code:

---

class y {
 public:
  x obj_x;
};

---

#include-ing them to each other causes an #include loop. Is there any way around this?

Thanks for the help,

Bad idea from me....delete delete delete

One of them will have to contain a pointer to the other, otherwise the data structure expands recursively.

In one or two files, you can do this

Code:

---

class y;  // a forward declaration

class x {
 public:
  y *obj_y;
};

class y {
 public:
  x obj_x;
};

---

how do i use one class or function from another file?

Like this?

File b.h contains:

Code:

---

class y;  // a forward declaration

class x {
 public:
  y *obj_y;
};

---

File a.h contains:

Code:

---

#include "b.h"
class y {
 public:
  x obj_x;
};
