C++多态

有一个注意要点,必须用指针,不能用A a = B()的形式。

#include "stdafx.h"#include "Base.h"#include "Class2.h"int _tmain(int argc, _TCHAR* argv[]){    Base* base = new Class2();    base->Run();    //Base Class Run Function will print "Base"    //Class2 Class Run Function will print "Class2"    //Execute program print "Class2"    return 0;}
