为什么不能在c ++中将构造函数声明为static？ [英] Why can't constructor be declared as static in c++?

问题描述

我最近读完了第一卷。

I have recently finished reading the 1st Vol. of Thinking in C++ by Bruce Eckel and have now turned to applying the knowledge to some practical use.

我最近使用静态成员函数，并尝试使构造函数静态，为此编译器不开心。我检查了在书中的原因，但没有找到任何。

I was recently working with static member functions and tried making the constructor static, for which the compiler was unhappy. I checked for the reason in the book but couldn't find any.

任何人都可以解释为什么？

Can anyone explain why?

PS：在看到一些回应后，因为我知道C＃（和Java）允许构造函数声明为静态。

P.S.: After seeing some responses, I would like to mention that the confusion arises from my knowledge that C# (and Java) allows constructors to be declared as static.

推荐答案

构造函数的目的是初始化类的实例的内容。

The purpose of a constructor is to initialize the contents of an instance of the class.

静态方法没有与它们相关联的实例。

Static methods don't have an instance associated with them.

因此，没有一个静态构造函数。

Hence there is no such thing as a static constructor.
