推荐答案

答案是A和B ......



类可以有构造函数和析构函数。 （如果你可以构造它，你需要能够销毁它）

类是引用类型（值类型类似于int，long，short等）

类 DO 支持继承，它是OOP的基本概念。



我不确定辩论是什么。 C ++和C＃都支持类的继承。我能想到的唯一辩论是C＃不支持的多重继承和C ++。

The answer is A and B...

Classes can have constructors and destructors. (If you can construct it, you need to be able to destroy it)
Classes are reference types (value types are like int, long, short, etc)
Classes DO support inheritance, its a fundamental concept of OOP.

I'm not sure what the debate can be. C++ and C# both support inheritance on classes. The only debate I can think of is multiple inheritance which C# does not support and C++ does.
