如果有的话，iostream和STL之间有什么关系 [英] What is the relationship, if any, between iostream and the STL
问题描述
有人问过iostream
和STL之间的关系，如果有的话。我怀疑是iostream使用了STL提供的一些
功能，但是我没有真正知道
，这是我怀疑的基础。有人知道吗？请让你尽可能详细地回答
。
谢谢，
Bob

回答。
STL是第三方图书馆被带入标准的
库。它在某种程度上表现出来并与某些概念一起使用
当时在编译器库中并不存在（我不相信
有一个标准）。当STL成为标准的一部分时，实现库中的部分库变为更好地与STL中的
概念一起工作。这包括添加的字符串
迭代器和iostreams我相信 - 再次，迭代器添加。
现在人们说STL的日子它们通常意味着
标准库的C ++部分（换句话说不是C compat crap），其中iostreams
当然是其中的一部分。恕我直言，这个词应该被贬低但是
无论如何。

首先，''iostream''是标准库的一部分。如果通过STL获得
你的意思是标准图书馆，这是你的关系。
我不是说只是为了让你失望，从某种意义上来说，重要的是
设计意图溪流背后的哲学与图书馆的其他部分一致。
流以两种主要方式融入图书馆的其他部分：它们
定义（重载）运算符用于输入和输出类型定义
库中的库（std :: basic_string，一个），并且它们还提供
用于某些库算法的迭代器。此外，在流和区域设置之间有一定的链接（可以这么说）。
流是否可以使用库的任何其他部分<幕后的
是未指定的。他们可以使用标准C库提供的流功能
。至于排序，搜索，复制
和其他算法，我不明白为什么不。分配器和其他
内存管理的东西。

Someone has asked me what the relationship is, if any, between iostream
and the STL. My suspicion is that iostream uses some of the
functionality provided by the STL, but I have no actual kowledge on
which to base my suspicion. Anyone out there know? Please make you
answer as verbose as possible.
Thanks,
Bob

answer as verbose as possible.The "STL" was a third party library that was brought into the standard
library. It behaved in certain ways and worked with certain concepts
not necissarily in compiler libraries at the time (I don''t believe
there was a standard). When the STL became part of the standard
library parts of the implementation library changed to better work with
concepts in the STL. This includes string to which were added
iterators, and iostreams I believe - again, iterators where added.
Now days when people say "STL" they usually mean the C++ part of the
standard library (in otherwords not the C compat crap), which iostreams
are of course part of. IMHO the term should really be depricated but
whatever.

Please make you
answer as verbose as possible.First and foremost, ''iostream'' is part of the Standard Library. If
by "STL" you mean the Standard Library, here is your relationship.
I am not saying that just to wave you off, it''s important in the sense
that the design intent and philosophy behind streams is in tune with
the rest of the library.
The streams fit into the rest of the library in two major ways: they
define (overload) operators for inputting and outputting types defined
in the library (std::basic_string, for one), and they also provide
iterators for use in some library algorithms. Also, there is a certain
link (so to speak) between streams and locales.
Whether streams make any use of any other parts of the library
behind the scenes, is unspecified. They can use stream functionality
provided by the Standard C library. As to sorting, searching, copying
and other algorithms, I don''t see why not. Allocators and other
memory management stuff as well.
