当基类对象的虚表有多个对象的成员函数的时候，只需要查看具体虚函数反汇编call的eax值就可以判断出虚基类的真实对象身份。
class Person
{public: Person() : age(30)
{
}
virtual void print()
{
printf("The person‘s age = %d\n", age);
}
protected: int age;
};class Teacher : public Person
{public: virtual void print()
{
printf("The teacher's age = %d\n", age);
}
};class Student : public Person
{public: virtual void print()
{
printf("The student age = %d\n", age);
}
};Person* createRole()
{ new Teacher;
return new Student;
}class Person
{public: Person() : age(30)
{
}
virtual void print()
{
printf("The person‘s age = %d\n", age);
}
protected: int age;
};class Teacher : public Person
