typedef struct prototype?

[Dante]

I am having trouble compiling the following 2 structs because they
both refer to each other. Is it possible to have some kind of struct
prototype to get this to compile? I tried "struct Object_Children;" at
the top line, along with a few other things, but I still get compile
errors.

typedef struct _Object
{

Object_Children children;

} Object;


typedef struct _Object_Children
{

Object *children_array; //array of Objects

} Object_Children;

typedef struct _Object_Children

} Object_Children;

struct Object;

struct ObjectChildren
{
Object* childrenArray;
};

struct Object
{
ObjectChildren children;
};

-- or --

struct Object
{
struct Children
{
Object* childrenArray;
};

Children children;
};

Also, instead of raw array of children, consider using

std::vector<Object> children;
