سلام دوستان
پروژه تحلیلگر لغوی زبان سی پلاس پلاس مربوط به درس طراحی کامپایلر رو پیاده سازی کردم کامل اجرا میشه و مشکلی نداره فقط قسمت خطایاب خطاهای لغوی رو نمیتونه تشخیص بده و نمیدونم مشکل از کجاس لطفا کمکم کنید...خیلی عجله ای و اورژانسی هست
:17::17::17:
قسمت های مربوط به خطایاب رو کامنت here گذاشتم
