C++ "class Foo return Bar" and "class Bar return Foo" possible?

Is it possible to define C++ classes Foo and Bar s.t.

class Foo {
  Bar makeBar();
};

class Bar {
  Foo makeFoo();
};

?

Thanks!

Yes it is, you just have to put forward declarations at the top.

class Foo;
class Bar;

class Foo {
  Bar makeBar();
};

class Bar {
  Foo makeFoo();
};

Yes. You can do it with a forward declaration.

For example, in Foo.h, add:

class Bar;

class Foo {
    Bar makeBar();
};
