为什么一个人不能实例化一个抽象类的对象 [英] Why can't one instantiate an object of an abstract class

问题描述

嗨！
为什么不能实例化抽象类的对象?
提供编译器的语句视图.

感谢您的时间！您必须创建一个基于抽象思想的真实类，才能实例化它.这与编译器无关，它是 C ++编程语言 [ ^ ].

以下是在Wikipedia上发现的一种独立于语言的良好语言: http://en.wikipedia.org/wiki/Abstract_type [^ ].

最好的问候，

C ++中的抽象类没有足够的信息来实例化有效对象.

Hi!
Why can''t one instantiate an object of an abstract class?
Give compiler view of statement.

Thanks for your time!

解决方案

Because it is abstract which in simple terms means not real, or an imaginary thing. you have to make a real class that is based on the abstract ideas to be able to instantiate it. This has nothing to do with the compiler, it is one of the rules of The C++ Programming Language[^].

Here is a good language independant descritpion found on Wikipedia: http://en.wikipedia.org/wiki/Abstract_type[^].

An abstract class in C++ does not have enough information to instantiate a valid object.
