静态初始化与动态初始化 [英] static initialisation vs dynamic initialisation

问题描述

为什么，在C ++中，我们更喜欢静态初始化到动态初始化？
如果静态初始化是如此高效，那么为什么新的语言如Java，C＃使用动态初始化？

Why, in C++, do we prefer static initialization to dynamic initialization? Whats the big deal?if static initialization is so performant then why do new languages like Java, C# use dynamic initialization?

推荐答案

我们没有。我们喜欢自动初始化 - 即在堆栈（而不是堆）创建对象。如果我们这样做，他们的生命是为我们管理。这是C ++对Java的许多优点之一。至于Java为什么这样，你应该问设计师，但我想，这是为了简化垃圾收集（同时引入许多其他问题）。

We don't. We prefer automatic initialisation - i.e. creating objects on the stack (as opposed to the heap). If we do that, their lifetimes are managed for us. This is one of many advantages that C++ has over Java. As to why Java works like this, you ought to ask the designers, but I'd guess that it is to simplify garbage collection (while introducing lots of other problems).
