这些模板的东西很好......对吗？ [英] These template things are good...right?

问题描述

也许我只是有点沮丧，我很快就会意识到明确的事实

，但是现在我对这个价值有一些严重的疑虑

投入大量时间和精力进行模板编程。我只是完成阅读_C ++模板的前12章：完整的

指南。当我阅读这些章节时，有一件事让我印象深刻，那就是我对C ++的了解程度不高。我_know_核心语言规范是

包含在有限文档中，但我有时会感觉到C ++

需要无限量的学习。


主要的C ++语言（没有模板）本身就很强大且非常强大。有很多方面我还没有完全掌握。虽然我会批准使用模板可以帮助

支持其中的一些技能，但我不得不怀疑模板真的是多么有用。
。我发现使用模板的代码经常不会像我期望或想要的那样表现为
。一个例子是std :: for_each算法。我经常在其他语言中使用

- 每个成语，并且还使用Qt提供的Cpp

实现（尽管这在
$ b中有很大的局限性） $ b自己的权利）。然而，std :: for_each对我来说几乎没用了。


一个知道如何使用模板的程序员会非常好吗？ />
比那些坚持使用C ++的传统OOP方面的人更有效率吗？

Perhaps I''m just a bit frustrated, and I will soon realize the clear truth
of the matter, but right now I have some serious misgivings about the value
of investing a lot of time and effort into template programming. I just
finished reading the first 12 chapters of _C++ Templates: The Complete
Guide_. One thing that struck me as I read these chapters is how much I
didn''t know about C++. I _know_ the core language specification is
contained in a finite document, but I sometimes get the sense that C++
requires an infinite amount of learning.

The primary C++ language (without templates) is substantial and quite
powerful in itself. There are many aspects of that which I have yet to
fully master. While I will grant that working with templates can help
shore up some of those skills, I have to wonder how useful templates really
are. I have discovered that code using templates can frequently not behave
as I expect or want. An example is the std::for_each algorithm. I use the
for-each idiom frequently in other languages, and also use the Cpp
implementation provided with Qt (though that has significant limitations in
its own right). The std::for_each, however, has proved virtually useless
to me.

Will a programmer who knows how to use templates very well be significantly
more productive than one who sticks to the traditional OOP aspects of C++?

在什么团队中，做什么？ IOW，是的，如果使用模板是那个程序员需要的
。不，如果使用模板不在他/她的日常活动中。


但是，请考虑一下你自己写的内容：在阅读本书时

模板你已经发现了多少你不知道核心

C ++语言。可以想象，坚持使用C ++的传统OOP方面的人。实际上并不像知识渊博那么bb在哪里核心 C ++比人们认为的要多。

In what team, doing what? IOW, yes, if using templates is what is
required from that programmer. No, if using templates is not in
his/her everyday activity.

However, consider what you yourself wrote: while reading the book on
templates you have discovered how much you didn''t know of the "core"
C++ language. It is conceivable that the "one who sticks to the
traditional OOP aspects of C++" is actually not as knowledgeable
where the "core" C++ is concerned than one thinks one is.

Can you learn to read a human language and claim proficiency in it
without, say, being able to talk? There were people who were very
versed in a foreign language without knowing how the words they read
or write are pronounced. Are they missing much? I don''t know. How
do you actually measure that? What I can say is that their knowledge
is incomplete and very artificial. They are definitely missing some
jokes based on how words are pronounced... Of course, if they stick
to the traditional scientific language, they can even be productive
in an environment where they don''t need to talk or understand speech
or understand jokes based on word play.

Does that answer your concerns?

对于模板的更高级使用，如果您使用的编译器

符合标准，则更简单，否则它可以是

令人沮丧。例如，你引用的模板书很少

也许这对许多人来说是显而易见的，但是OTOH可能不是这样，如果你在

这个曾经使用过的职位一个较旧的编译器。

For more advanced use of templates, it is much simpler if the compiler
you are using is reasonably standard conformant, else it can be
frustrating. For instance the Template book you cite would be little
use in practise with VC++6.0 or gcc < 3.0 methinks.

Maybe that''s obvious to many, but OTOH it may not be so if you are in
the position of only ever having used an older compiler.
