为了搞清楚VC中类的实现专门写了一个最简单的类，用来观察它的实现过程，代码如下：
// test.cpp : Defines the entry point for the console application.
//
#include "stdafx.h"
#include "CTest.h"
int main(int argc, char* argv[])
{
CTest aTest;
aTest.a(1,2);
return 0;
}
// CTest.h: interface for the CTest class.
//
//////////////////////////////////////////////////////////////////////
#if !defined(AFX_CTEST_H__2CCCDCFC_6C3A_48BC_9CD0_E7A8E63431D9__INCLUDED_)
#define AFX_CTEST_H__2CCCDCFC_6C3A_48BC_9CD0_E7A8E63431D9__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
class CTest
{
public:
CTest();
virtual ~CTest();
public:
void b();
void a(int one,int two);
};
#endif // !defined(AFX_CTEST_H__2CCCDCFC_6C3A_48BC_9CD0_E7A8E63431D9__INCLUDED_)
// CTest.cpp: implementation of the CTest class.
//

CTest::CTest()
{
}
CTest::~CTest()
{
}
void CTest::b()
{
printf("b is be called by a");
}
void CTest::a(int one,int two)
{
printf("call b");
b();
}
下面是相应的反汇编代码：
--- D:myown est est.cpp ------------
1: // test.cpp : Defines the entry point for the console application.
2: //

4: #include "stdafx.h"
