c ++的新功能？ [英] new features in c++?
问题描述
几年前我读了一本C ++书，学习了C ++的基础知识。从那时起，我几乎没有完成C ++编程
。现在我注意到例外，模板
和using namespace语句。这些东西是新增的吗？还是他们一直都在那里？
I read a C++ book some years ago and learned the
basics of C++. And I''ve almost done no C++ programming
since then. Now I notice stuff like exceptions, templates
and the using namespace statement. Are these things
new additions, or have they been there all along?

这取决于多少几年是。当前的C ++在1998年的b $ b $标准化，并且新的标准（有时称为C ++ 0x）将在未来几年内出现在
之内。尽管该语言在1998年的b
中标准化，但在编译器实现者之前可能还需要一段时间。实际上，我甚至不确定是否有100％完全符合标准的编译器，尽管从我看到的Comeau
编译器最接近（它是我所知道的唯一一个支持
模板的export关键字。

将''invalid''替换为''net''以回复
It depends on how many "some years" is. Current C++ was standardized in
1998, and a new standard (sometimes called C++0x) is due to come out
within the next few years. Even though the language was standardized in
1998, it may have been a little while before compiler implementers
caught up. Actually, I''m not even sure if there is a 100% fully
standards-compliant compiler, though from what I have seen the Comeau
compiler comes the closest (it''s the only one I know of that supports
the "export" keyword for templates).

Replace ''invalid'' with ''net'' to reply

他们自1997年11月以来就存在（实际上有一段时间
之前），当第一个C ++国际标准被批准时。
许多编译器也在之前实现了这些功能。

我没有回复最热门的回复，请不要''请问
They have existed since November 1997 (and actually some time
before), when the first C++ International Standard was approved.
Many compilers implemented those features before as well.

这取决于多少几年？是。当前的C ++已经标准化了1998年，

It depends on how many "some years" is. Current C++ was standardized
in 1998,
实际上，_current_ C ++大约在2003年，当时进行了一些更正
标准。
[...]
Actually, _current_ C++ is circa 2003, when some corrections were made
to the Standard.
