- 语法分析是编译程序的核心部分。语法分析的作用是识别由词法分析给出的单词符号序列是否是给定的文法的正确句子。目前语法分析常用的方法右自顶向下分析和自底向上分析两大类。 确定的自顶向下方法,是从文法的开始符号,考虑如何根据当前的输入符号(单词)唯一的确定选用哪个产生式替换相应非终结符往下推导。 LL(1)文法是一种确定的自顶向下的分析方法。 LL(1)的含义是:第一个L表明自顶向下分析从左向右扫描输入串,第二个L表明分析过程中将用最左推导,1表明只需向右看一个符号便可以决定如何推导即选
mlex
- 词法分析器设计 读入源程序,每从源程序中发现一个符号串构成一个单词,即输出一个二元式(单词种别,单词值)。其中单词种别用整数说明。标识符的单词值为其在符号表中的记录号。非负整常数的单词值为其在常数表中的记录号-Lexical analyzer designed to read into the source code, each symbol from the source found in a string constitutes a word, that is, the output o
