السلام عليكم ورحمه الله وبركاته
اخواتى فالله
:)
اريد ان اقدم لكم برنامج صغير بلغه السى بلس بلس
هذا البرنامج كان مطلوب منى فى الكورس بتاع OOP اثناء الكليه
والحمدلله تعالى عملته فى ساعه بعد ما اخدته :lol: :lol:
ولكن الان وانا ادعبث فى ملفاتى وجته قولت اشاركم بيه
لعل وعسى ان يستفيد منه احد
فهو للاستفاده فقط
البرنامج يعتبر شرحه فى صورتين فقط مع القليل من الكلام عنه
والتفاصيل الاخرى فقد قومت بوضع التعليقات على الكود الان حتى اذ قرأه احد يفهمه ويستوعبه ان شاء الله
البرنامج يتحدث عن ان هناك بيانات طلاب مخزنه فى ملف واريد ان اصنع منها تقريرا بشكل منظم فى ملف اخر
هذا هو الملف المخزن به البيانات موضوع بالصوره التاليه
كما موضحه التفاصيل على البيانات الموجوده فى الملف
ونريد ان نخرجها بهذه الصوره
اتمنى ان يفيدكم هذا البرنامج الصغير واى سوال ان شاء الله اجاوب عليه
للتحميل
فاليكم الكود للاطلاع عليه فقط
هو عباره عن Student class & it's implementation & main file
Student.h
