这是我们老师留的作业，还算不错我给完成了，希望给想做的朋友一点启发...

1、构造该算符优先文法的优先关系矩阵或优先函数； 2、输入串应是词法分析的输出二元式序列，即某算术表达式“实验项目一”的输出结果。输出为输入串是否为该文法定义的算术表达式的判断结果。 3、算符优先分析过程应能发现输入串出错。 -1, construction of the operator the priority of the priority relation matrix grammar or priority function 2, input strings should be the output of lexical analysis of binary sequence, that is, the arithmetic expression of a

语法分析器，对已给pascal语言文法，构造LL(1)分析表，编制语法分析程序，要求将错误信息输出到语法错误文件中，并输出分析句子的过程-Parser that have been to the pascal language grammar, structure LL (1) analysis table, the preparation of parsing procedure that requires the output to the error message syntax error file, and output analysis of the process of sentence

PL/0语言可以看成PASCAL语言的子集，它的编译程序是一个编译解释执行系统。PL/0的目标程序为假想栈式计算机的汇编语言，与具体计算机无关。 文件说明: PL.htm---PL/0语言基本原理 pl0.h---定义 PL0.cpp---实现 testPl0.cpp---使用方法举例 testPas.txt---一个LP/0语言源程序-PL/0 language may regard as the PASCAL language the subset, its compiler is a translation explanation execution system. The PL/0 target program for the imaginary stack type computer assembly language, has nothing to do with with the concrete computer. Document explanation that, PL.htm---PL/0 language basic principle pl0.h--- defines PL0.cpp--- to realize the testPl0.cpp--- application method to give an example testPas.txt--- a LP/0 language source program
