父类Dad中所有函数为纯虚函数,定义子类Son,子类实例化的地方提示allocating an object of abstract class type“XXX” 原因如下: 在实例化的时候: (a)一定要确保父类所有的纯虚函数都要被实现,否则子类依然不能被实例化; (b)一定要确保继承的虚函数确保函数的入参类型,返回值类型一致,否则父类的虚函数没有实例...
C/C++ allocating an object of abstract class type 原因:一般是因为该类继承的抽象类中,有未实现的抽象函数。在实例化的时候: (a)一定要确保父类所有的纯虚函数都要被实现,否则子类依然不能被实例化; (b)一定要确保继承的虚函数确保函数的入参类型,返回值类
C++ 在 cocos2d-x中,报错:allocating an object of abstract class type “xxxx” 通常是该类,有未实现的虚函数,需要实现。
c++ 在cocos2d-x中,报错:Allocating an object of abstract class type“xxxxx” 1.在该类中,有未实现的虚函数,需要实现,或者是 父类里的虚函数子类没有实现造成的。 2.还有的情况是,在编写代码的过程中,虚函数在父类和子类中的函数名不一样,这 3.可能粗心造成的,我就是这样,在子类中把函数名给改了,所...

1) based on what you mentioned, I CANNOT allocate an object/variable based on the class(*) and its dynamic argument type? 2) If that is the case, I am struggling to understand what is the purpose for the unlimited polymorphic feature, or when is it beneficial to use? ...
