trouble with assigning values to tokens flex++ bison++

Hello everybody!

I'm writting a HTML parser using flex++ and bison++. The trouble is that I cannot assign values to
the tokens. I know how this works in C, but is there some other way to do this in C++?

I would really appreciate if you could take a look at this code
(it's just a small example of the original code).

parser.y
-----------------
%name Parser
%define MEMBERS \
~Parser() {} \
private: \

yyFlexLexer lexer;
%define LEX_BODY {return lexer.yylex();}
%define ERROR_BODY {}
%header{
#include <iostream>
#include <fstream>
#include <FlexLexer.h>
#include <cstdlib>
#include <stdio.h>

#include <string>
#include <string.h>
#define YYSTYPE char *
using namespace std;
%}

%union {

const char *str;
}

%{
ofstream out;
%}
%token <str> STRING

%start html_start
%%
html_start

: text {

$<str>$=$<str>1;
out<<" text2 "<<$<str>$;
}
|{out<<" text1 ";}

;

text

: STRING {$<str>$ = $<str>1;
}
;
%%
int main(int argc, char ** argv )
{
Parser parser;
ifstream inp;
string myFileName;
myFileName = "mydata.txt";
inp.open(myFileName.c_str(), ifstream::in);

inp.close();
inp.clear(ios::failbit);
out.open("mydata.txt", ofstream::out);
parser.yyparse();
return 0;
out.close();
}


scanner.l
------------------
%option c++
%option noyywrap

%{
#include<sstream>
#include <iostream>
#include "parser.h"
#include <cstdlib>
#include <fstream>
#include <malloc.h>
#include <string.h>
yy_Parser_stype yyval;

%}

letter [_a-zA-Z]
DIGIT [0-9]
%%

{letter}({letter}|{DIGIT})* {
yyval.str=(yytext);
return ( Parser::STRING);
}

<<EOF>> {
yyterminate();
}

%%

In principal, you can compile C code as C++ code without problems.

Please use code tags when you post code. What you've posted doesn't look like C++ code to me.

I've manage to compile it but it's not working.

I will use it in the future. It is c++...

It looks more like lex/yacc code to me rather than C++
