السلام عليكم ورحمة الله وبركاته اليوم اقدم لكم برنامج بسيط جدا تطبيق علي linked list بناء علي طلب اصحابي سنه تانيه علشان امتحان العملي دي حاجه بسيطه انا عملتها اتمني الاستفاده البرنامج بيوضح العمليات التي يمكن تطبيقها علي ابسط انواع linked list وهي
عمليه الانشاء
عمليه الاضافه في اول القائمه
عمليه الاضافه في اخر القائمه
عمليه البحث
عمليه الترتيب
عمليه الحذف
سوف نقوم بعمل برنامج يطبق هذه العمليات البرنامج بسيط جدا عن الطلاب هندخل بيانات طالب او اكتر ونطبق العمليات السابقه عليه

واخيرا ابقوا عدلوا شكل البرنامج علشان اللخبطه اللي بتحصل اثناء الرفع والسلام عليكم ورحمة الله وبركاته
