السلام عليكم ورحمة الله
ياليت لو أحد منكم يقدر يساعدني و يشرح لي هالبروجيكت لان حايس فيه 1- ماعرفت كيف اخليه يرجع للقائمة الرئسية 2-ماعرفت لل exit اللي هيا تحسب كل اللي دخلتو ويطلعو في جدول و يتقفل البرنامج 3- واخر نقطة للمتغيرات اللي هيا حق (####-###-##) الجوال والمتغيرات اللي تحت الجوال مني عارف كيف اخلي المستخدم يكتب اللي يبغاه مثلا اقعد اخليه يكتب اذا ظغط انتر ينتقل للمدخل التالي , اتمنى الفزعة ياشباب الكود اللي ارسلتو ماهو كامل بس اتمنى توضيح للثلاثة نقاط بس .

راح أكون شاكر لكم

1- لازم يكون nested loops فلازم زر الريترن يخلي شرط اللوب خطأ فيرجع للوب اللي شمله..
2- نفس طريقة count++ لكل شيء، واخر شيء تجمعهم.
3- لـ ##-###-#### استخدم سترنق.. وبس
للمعلومية... input.next(); هذي تقرا كلمة وحدة
اما
input.nextLine(); هذي بتقرا السطر كامل..

بالتوفيق، التسليم اليوم ;)
