エラーC2146とC4430

Question

まず：申し訳ありません私の悪い英語=（（

Sencond：

ここに私のコードは "GLOBAL.H" にあります：

#pragma once 
class GlobalVariable 
{ 
public: 
    GlobalVariable(void); 
    ~GlobalVariable(void); 

    //------------------------------------------------ 
public: 
    double pixelWidth;  // do rong cua 1 pixel tren Viewport 
    double pixelHeigh;  // do cao cua 1 pixel tren Viewport 

public: 
    Point oldPoint, tempPoint; 
    Circle oldCir,  tempCir; 
    DaGiac oldDaGiac, tempDaGiac; 
    Color oldObjColor,tempObjColor, OxyColor; 

}; 

class Point 
{ 
public: 
    Point(void); 
    ~Point(void); 

    double x,y;   // toạ độ (x,y) 
}; 

class Color 
{ 
public: 
    Color(void); 
    ~Color(void); 

    double R,G,B;   // màu (R,G,B) 
}; 

class DaGiac 
{ 
public: 
    DaGiac(void); 
    ~DaGiac(void); 

    int numOfPeak; //so' dinh? 
    Point peakArr[10]; // ve da giac canh so dinh toi da la 10 
}; 

class Circle 
{ 
public: 
    Circle(void); 
    ~Circle(void); 

    Point centre; 
    double radius; 

};

と私はいくつかのエラーがあります:(

しかし、GlobalVariableクラスを削除した後に！ Pointクラス、Colorクラス、DaGiacクラス、Circleクラスのみ存在する！それにはエロがありません！ 理由を教えてください。そのエラーを中核にする方法は？してください=（（それらは後GlobalVariableクラスを定義しているので

Answer 1

コンパイラは、他のクラスを「見る」ことができない。そのように、ファイルの末尾に全体GlobalVariableクラスを移動するクラスのすべてのこと
