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

[ahmadii]

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.

[Borland.C]

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

[bendavis]

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

[bendavis]

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

[mahak006]

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 .
