//指针的引用，把identity*当作一个类，类名后加&，就是引用这个类的对象，
//这里是以引用的方式来接收identity类的指针实参
//加不加&的区别就在于，不加重新开辟空间，并创建一个名为manager的指针，
//这个指针内部存放的数据是对实参数据的拷贝（拷贝了一块地址编号）
//加了&，如果不考虑引用的本质，那么就相当于给实参指针起了第二个名字，叫做manager，
//我们可以通过manager这个名字直接去调用实参
//形参是n级指针，实参也是n级指针时，形参指针不会指向实参，而是进行对实参的拷贝，
//如果想让指针指向指针，那么形参指针必须比实参指针高一级

//多态的巧妙之处就在于，可以在不确定要调用那个子类函数时使用多态
