这可能会让你感到困惑的是区分大小写 ;？

Could it be you''re confusing that with "case-sensitive"?

是的它可能是，但我正在试图解释它们与

的不同之处感觉并且不了解自己。

Yes it could be, but I''m trying to explain how they are different in
that sense and do not know myself.

你指的是语法吗？我怀疑

的几个部分是使它对上下文敏感的语法，但是我会说一个人需要的

事实。知道一个给定的令牌是否是一个类型名称，而解析的是b $ b，是主要原因。两种语言都有typdef关键字

通过定义新的typname来引入上下文敏感性。而且C ++有很多其他的构造，我猜它会这样做，比如模板。

Are you referring to the grammar(s)? I suspect there are several parts of
the grammar(s) that make it context sensitive, but I''d say off-hand that the
fact that one needs to know if a given token is a typename or not, while
parsing, is the main reason. Both languages have the typdef keyword which
introduces context sensitivity by defining a new typname. And C++ has a lot
of other constructs that I''d guess make it so, such as templates.

Search on groups.google.com, and you''re sure to get a lot of hits.
