C－Minus (或简称为C－)，是一种适合编译器设计方案的语言，包括函数和数组。本质上它是C的一个子集，但省去了一些重要的部分。本部分内容包括，首先，列出了语言惯用的词法，包括语言标记的描述。其次，给出了每个语言构造的BNF描述，同时还有相关语义的描述。最后，给出了C－的示例程序，可以用这两个程序做为输入，检查自己的编译系统的有效性。(C-Minus (or C-), which is suitable for the compiler design language, including function and array. It is essentially a subset of C, but it saves some important parts. This part includes, first, a list of language idiomatic phrases, including the descr iption of language markers. Secondly, the BNF descr iption of each language structure is given, and the descr iption of the related semantics is also described. Finally, given C examples of procedures, can use these two programs as input, check the validity of their compilation system.)
