您好，
如果您想要解析艺术表达式，请阅读RPN -
反向波兰语符号，这是一个很好的方法，实现起来很简单。

您想知道什么样的事情？运算符优先级？还有别的吗？
或者他可能想要一个如何在C中编写自己的解析器的例子。
问题就是那么模糊。
在任何情况下，ANSI C yacc语法都可以在线免费获得：

这个语法应该告诉你关于如何解析一个C / /
翻译单元的所有知识。如果你不知道yacc或BNF，这个网站可能是

Can someone suggest some good links for the "beginners"
about how expressions are parsed in C ?

What sort of thing do you want to know? Operator precedence? Something else?

Hello,
If you''re looking to parse artihmetical expressions just read about "RPN -
Reverse Polish Notation", it is a good method and simple to implement.

Or he might want an example of how to write his own parser in C. The
question is just that vague.
In any case, an ANSI C yacc grammar is available online for free:
http://www.lysator.liu.se/c/ANSI-C-grammar-y.html
This grammar should tell you all you need to know about how to parse a C
translation unit. If you don''t know yacc or BNF, this website may be of
