是否有标准的C ++语法？ [英] Is there a standard C++ grammar?

问题描述

标准是否指定官方的C ++语法？

Does the standard specify the official C++ grammar?

我搜索过，但没有找到它。

I searched, but did not find it anywhere.

另外，我想详细了解一下C ++语法，比如它所属的语法类别等等。任何指向正确方向的链接都会有所帮助。

Also, I wish to read a bit about C++ grammar in detail, like which category of grammars it falls in, etc. Any links pointing me in the right direction would be helpful.

按类别，我的意思是

取自这里。

推荐答案

是的，

语法在整个标准中有详细的描述，并在附录A：语法摘要（在C ++ 03标准和C ++ 0x final final draft draft。）

The grammar is described in detail throughout the standard and is summarized in Appendix A: Grammar Summary (it's Appendix A in both the C++03 standard and the C++0x final committee draft).

您可以，或者您可以下载C ++ 0x FCD （它是该页上的文档n3092）。

You can purchase the C++03 standard or you can download the C++0x FCD (it's document n3092 on that page).

它是什么类别？问题， C ++语法是不是 context-免费（也可以看到在这个问题的答案中链接的问题;他们有与C ++语法和解析C ++相关的问题的其他示例）。

To answer the "what category is it in?" question, the C++ grammar is not context-free (also see the questions linked in answers to that question; they have additional examples of issues related to the C++ grammar and parsing C++).
