I need help, now im trying to made the main.cpp code in visual studio $2022.$ i already made a $.$l file and y$.$ file using bison and flex. The $.$l file code is the following

$\%\{$

#include "cminusminus$\_$parser.tab.h$"//$ Generated by Bison

$\%\}$

$\%\%$

$"+"\{$ return PLUS; $\}$

$"-"\{$ return MINUS; $\}$

$"*"\{$ return MULTIPLY; $\}$

$"/"\{$ return DIVIDE; $\}$

INT $\{$ return INT; $\}$

$[$a$-$zA$-$Z$][$a$-$zA$-$Z$0-9]*\{$ return ID; $\}$

$[0-9]+\{$ return NUMBER; $\}$

$"/*"([^*]|[\backslash$r

$]|(\backslash *+([^*/]|[\backslash$r

$])))*"*+"\{/*$ Ignore comments $*/\}$

$"[\backslash$t$\backslash$r

$]+"\{/*$ Ignore whitespace $*/\}$

$.\{/*$ For any unrecognized character $*/\}$

$\%\%$ and $.$y file is the following $\%\{$

#include

#include

#include "cminusminus$\_$parser.tab.h$"$

extern int yylex$()$;

extern int yyparse$()$;

extern FILE$*$ yyin;

void yyerror$($const char$*$ s$)$;

$\%\}$
