Re: forward declaration of an enumerated type

Hi Ben,
Thank you very much for your pointing out.

I am awfully sorry for this bad reply. I misunderstand the conception
before.
No matter struct and enum types can be forwarded declared. I performed a
test for clarifying my mistake and hope that it helps for this issue.

//=====x.h=============
#pragma once
struct X {int a;};

enum Color{
Red = 0,
Blue = 1,
Green = 2
};

//======y.h==============
#pragma once

struct X;
enum Color;
void print(X& x);
void print(X& x, ENU enu);

//======y.cpp=========
#include "stdafx.h"

#include "X.h"
#include "Y.h"

void print(X& x)
{
    printf("%d",x.a);
}

void print(X& x, Color color)
{
    printf("X:%d, Color:%d",x.a,color);
}

//=======main.cpp===========
#include "stdafx.h"
#include "X.h"
#include "Y.h"

int main(void)
{
  X x;
  x.a = 100;
  Color color;
  color = Color::Green;
  print(x);
  print(x,color);
  return 0;
}

Hi, David, I am sorry for misleading you in my previous bad reply and
sincerely hope that you can see this reply and post back if you have any
other questions or concerns.

Best regards,
Charles Wang
