السلام عليكم
عندي هذا السؤال
و هذا الاوت بوت
فكرة البرنامج انه الطالب يبحث عن معلومات استاذة ( اسم المس و رقم التلفون و اي دي الاستاذة) البحث عن طريق رقم روم الاستاذة كتبت الكود باستخدام الدبلي لنك لست
لما وريته الاستاذة قالت ضروري انك تضيفي انسيرت مثود ع اساس انه المستخدم يقدر يضيف معلومات استاذات جدد غير الموجودات باللستة اللي بالبرنامج
لو ما اضفته ما راح تقبل مني البرنامج :( التسليم بعد كم يووووم
اضفت انسيرت مثود بس عندي بعض الايرر
و هذي الاربعة كلاسات للبرنامج
