Description: 本课程设计即为词法分析阶段。词法分析阶段是编译过程的第一个阶段。这个阶段的任务是从左到右一个字符一个字符地读入源程序,对构成源程序的字符流进行扫描和分解,从而识别出一个个单词(也称单词符号或符号)。如保留字(关键字或基本字)、标志符、常数、算符和界符等等。-the curriculum design shall lexical analysis stage. Lexical analysis stage of the process is to compile the first phase. This phase of the task whatever it is a character to a character read source code, which constitute the source of the characters flow scanning and decomposition, which identified a 000 word (also known as a symbol or word symbol). Words such as reservations (keyword or basic word), URI, constant, operator and so on community website.

Description: 语法分析程序
利用C++(或C)编制确定的自顶向下预测分析语法分析程序,并对简单语言进行语法分析。
待分析的简单语言的语法若文法G[ E]为:
(1) E –> TE’
(2) E’ –> +TE’
(3) E’ –> e
(4) T –> FT’
(5) T’ –> *FT’
(6) T’ –> e
(7) F –> (E)
(8) F –> i
实验说明
具体要求如下:
(1)用可视化界面分步骤实现,显示输出每一步的处理结果。
(2)首先按照判别步骤判断给定文法是否LL(1)文法。
(3)给出文法的预测分析表。
(4)编写预测分析程序,输出句子的分析过程。
(5)输入源文件串,以“#”结束,如果是文法正确的句子,则输出成功信息,打印“SUCCESS”,否则输出“ERROR”。
例如:
输入文件: i+i*(i+i) #
输出 success
过程:略;
输入文件: i+ii#
输出 error-yufafenxi
