Parser Generator is a YACC and Lex programming tool for Windows. As well as including a Graphical User Interface, the software also includes two versions of YACC and Lex, called AYACC and ALex. Parser Generator is able to generate C, C++ and Java parsers and lexical analysers. This includes both Unicode and Multibyte Character Set (MBCS) variants. In your applications you can create multiple, thread safe, instances of these parsers and lexical analysers. Direct support is provided with Parser Generator for Visual C++ and Borland C++ and C++Builder.

Thanks for your appreciation Big K, but the word 'Guru' will be too big for me. I am also beginner in Linux and i am sure many people here will be knowing more then me. Cheers to all CE's

But i am always ready for any such knowledge sharing activities.

hi.i dont think i understood this software ie parser generator too good.do i have to store the TC and this parser generator software in same folder?

i have to write a source program and have to identify the tokens of my c input file.say my lex program is
%{
%}
%%
"girl1" !"girl2" {printf("noun");}
%%
void main()
{FILE *fp1;
fp1=fopen("in.c","read");
yyin=fp1;
yylex();
}
and my c program is
in.c

girl1 sings girl2 dances

so my i first compile my lex program.then will the tokens be generated automatically?incase of unix,lex tool ie lex prgname.l is used right.what do i do in this case?
