Linux或Windows中的C ++ [英] C++ in Linux or Windows
问题描述
在Linux或Windows中编写C ++有什么区别吗？
我被告知这只是可用IDE的问题（两者都是日食）
平台，但只有Visual Studio for Windows）但还有其他
techincal / syntatical /标准库函数的区别吗？

Are there any difference between writting C++ in linux or Windows?
I was told that it was only a matter of available IDE''s (eclipse for both
platforms, but only Visual Studio for Windows) but are there other
techincal/syntatical/standard library function differences?

当你需要特定于平台的api时，你会遇到不同之处。因为你住在c ++标准沙箱里，所以你很安全，尽管
有扩展沙箱边界的库可以轻松实现
跨平台开发。

You''ll encounter the difference when you need platform specific api. As
long as you dwell inside the c++ standard sandbox, you''re safe, although
there are libraries that extend the boundaries of that sandbox to ease
cross-platform development.

嗯，从理论上讲，语法和
标准库功能应该没有区别。但是要记住一些事情：
1）语言规范通常不要求*实现*
语言/库功能超出所需功能，所以
不同的编译器 - 可能在同一平台上 - 可能会以不同方式实现
功能（例如，这可能会在时间上显现出来/
内存使用某些功能）。此外，有很多实例可能是未定义的行为。在语言规范;如果你点击
中的一个，那么所有的赌注都会被取消，你不可能期望
平台/编译器得到类似的结果。
2）编译器可以提供语言的非标准扩展和
标准库（希望它们还能提供一种关闭b / b
的方法非标准功能和强制执行严格的语言/标准库
合规性。
3）可能存在完全不同的操作系统特定分类
可用于各种平台的库，特别是在C ++标准不提供功能的领域（例如GUI，线程，
进程间通信，网络，等等。）。其中一些库
可能（尝试）是跨平台的，而其他的则不是。
如果您坚持严格的语言标准合规并避免非
便携式库然后，您应该在跨平台的语言中遇到没有显着差异的
;当然这可能是不可能的，
取决于你想要编程的东西。
IDE是（方便的）问题 - 你可能不会需要/想要使用一个

Well, in theory there should be no difference in terms of syntax and
standard library functionality. Some things to bear in mind, though:
1) The language specification generally does not mandate *implementation*
of language/library features beyond required functionality, so that
different compilers - possibly on the same platform - may well implement
features differently (this may, for example, manifest itself in time/
memory usage of some function). Also, there are very many instances of
potential "undefined behaviour" in the language spec; if you hit one of
these all bets are off and you can''t expect similar results across
platforms/compilers.
2) Compilers may provide non-standard extensions to the language and
standard library (hopefully they will also provide a means of "turning
off" non-standard features and enforcing strict language/standard library
compliance).
3) There are likely to be wildly disparate assortments of OS-specific
libraries available for various platforms, particularly in areas where
the C++ standard does not provide functionality (eg. GUIs, threading,
inter-process communication, networking, etc.). Some of these libraries
may (attempt to) be cross-platform, others not.
If you stick to strict language standards compliance and avoid non-
portable libraries then, you should encounter no significant differences
in the language across platforms; of course this may not be possible,
depending on what you are trying to program.
IDEs are a matter of (in)convenience - you may not need/want to use one
(I don''t).

嘿 - 以为我是唯一一个。 Gvim并为我做好准备......
Heh - thought I was the only one. Gvim and make for me...
