用SLR1分析表达式文法，文法的产生式为 E->T|E+T T->F|T*F F->i|(E),Analysis with SLR1 expression grammar, generative grammar for E->T|E+T T->F|T*F F->i|(E)

该程序为一个手工编码实现的简单SLR语法分析器，其词法分析器调用接口为lex()，语法分析调用接口为SLR1()。-The program is a simple hand-coded implementation SLR parser, the lexical analyzer is called interface lex (), parsing call interface for the SLR1 ().

使用C++编写的编译器，里面 包括了词法分析程序scanner.cpp，无符号数识别程序ucon.cpp，算符优先法语法语义处理程序SF.cpp，SLR1语法语义处理程序SLR1.cpp。比较强大。源程序输入有program.txt，输出包括窗口和compiled.txt-Using C++ to write compiler, which includes lexical analysis program scanner.cpp the number of symbols identifica
