编译原理 课件 蛮实用的

用LL（1）法对布尔表达式的语法分析- (1) the law analyzes with LL to the Boolean expression grammar

词法分析程序设计 1、给出各单词符号的类别编码。 2、词法分析程序应能发现输入串中的错误。 3、词法分析作为单独一遍编写，词法分析结果为二元式序列组成的-Lexical analysis program design one, given the various types of code word symbols. 2, lexical analysis procedure should be able to detect errors in the input strings. 3, again as a separate lexical analysis prepared for morphological analysis of binary sequence composed of

这是一个用来生成表达工的值的程序 它可以输入8进制或十进制的数 建立一棵语法树 并返回表达式的值-This an expression used to generate value for the procedures it can be imported or 8 band of a few decimal establish a syntax tree and return to the value of the expression
