#include <iostream.h>
#include <objbase.h>
void trace(const char*pMsg){cout<<pMsg<<endl;}

interface IX
{
virtual void_stdcall Fx1() = 0;
virtual void_stdcall Fx2() = 0;

virtual void_stdcall Fy2(){cout<<"CA::Fy2"<<endl;}
};
int main()
{
trace("Client:Create an instance of component.");
CA* pA=new CA;
IX*pIX=pA;
trace("Client:Use the IX interface.");
pIX->Fx1();
delete pA;

return 0;
}

编译老是错误，不知道是怎么回事。在线等大家的答复中~~~~~~~~~~~~~~~~~~~~~~~

[珍惜生命远离CPP]

#include<iostream>
#include  <objbase.h> 
using namespace std;

void trace(const char*pMsg){cout <<pMsg <<endl;}

interface IX
{
    virtual void __stdcall Fx1() = 0;
    virtual void __stdcall Fx2() = 0;
};
interface IY
{
    virtual void __stdcall Fy1() = 0;
    virtual void __stdcall Fy2() = 0;
};
class CA:public IX,public IY
{
    virtual void __stdcall Fx1(){cout <<"CA::Fx1" <<endl;}
    virtual void __stdcall Fx2(){cout <<"CA::Fx2" <<endl;}
    virtual void __stdcall Fy1(){cout <<"CA::Fy1" <<endl;}
    virtual void __stdcall Fy2(){cout <<"CA::Fy2" <<endl;}
};
int main()

    trace("Client:Create an instance of component.");
    CA* pA=new CA;
    IX*pIX=pA;
    trace("Client:Use the IX interface.");
    pIX-> Fx1();
    delete pA;

    return 0;
