ذخیره اطلاعات در فایل و خواندن از فایل (کمک فوری)

با عرض سلام.من یه برنامه نوشتم که اطلاعات اساتید رو دریافت می کنه و یه سری عملیات روشون انجام میده حالا می خوام وقتی برنامه بسته میشه اطلاعات در یه فایل ذخیره بشه و وقتی برنامه باز میشه اطلاعات دوباره به برنامه برگرده.لطفا اگر کسی بلده سریع کمکم کنه برنامه رو ویرایش کنه.

به نظرم راحتر بود اگه به جای کلاس از struct استفاده می کردی و از توابع file
البته اگه اجباری در استفاده از کلاس نیست

کار با فایلها روش های زیادی دارد
ساده ترین دستور زیر است (به کمک فایهای متنی)
به کمک دستور fopen

نمی توان در این محیط خوب تایپ کرد مگرنه کد را با اخنصار مینوشتم

کد رو تو تگ C++‎ بذار . موقع تایپ کردن این تگ تو نوار ابزار تایپ تو فروم هستش . این طور کد خوانا تر می شه .
