حل جميع الـ sheets فى المنهج .

[عاصم]

سلام عليكم و رحمة الله وبركاته .

عاييزين بإذن الله نعمل هنا تجميع لحلول شيتات المنهج كلو
و عددهم 10 ان شاء الله .
طريقة الكتابة فى الموضوع كالتالى :
فى مشاركة محجوزة لكل sheet . ان شاء الله دى حنجمع فيها حلول المسائل ,
ياريت يا جماعة الهدف مش ان واحد بس يحط حلول .
ياريت كلو يشارك و منستناش الحلول من شخص بعينه
عشان اصلا المسائل يمكن اتحل تلتها ولا حاجة فى السكاشن او نصها . فعاييزين ناس كتير تشارك عشان نبقى متأكدين ان شاء الله من الحلول .
اى حل حيتحط لسؤال ( غير محلول ) حضيفه ان شاء الله فى المشاركة بتاعت رقم الـ sheet .

ياريت يا جماعة اللى يلاقى غلطة فى الحلول النهائية .
النهائية : يعنى اللى موجودة فى المشاركة الأساسية بتاعت الـ sheet يبعتلى على الخاص عشان اعدلها بسرعة .
و ياريت عدم وضع حلول لأى completed sheet عشان منزحمش الموضوع .
ياريت يا جماعة نشارك و نبقى interactive شوية
و جزاكم الله خيرا ان شاء الله .:)

بالنسبة لQ.4 sheet(1)
أما جيت أعمل build ظهرت الشاشة السودا كتبت رقم 37 مثلا ,الشاشة السودا قفلت ومجتش تانى
ليه بقا؟:011::011:

بالنسبة لQ.4 sheet(1)
أما جيت أعمل build ظهرت الشاشة السودا كتبت رقم 37 مثلا ,الشاشة السودا قفلت ومجتش تانى
ليه بقا؟:011::011:

ده ليه كدا :D
حطى نسخة من اللى موجود فى ال output لو سمحتى

[ريـــــــــــــمـ]

:petlya35ch:مانا مش بعرف

[ريـــــــــــــمـ]

هوه أصلا مفيش output
كل اللى طلعه enter the ASCII code in decimal:
أنا كتبت 37 ودوست enter
بس فالشاشة السودا راحت وحلفت ماهى راجعة تانى

[عاصم]

لما بتعملى ctrl + f5
بتظهر تحت لوحدها شاشة ال out و ممكن تاخدى اللى فيها كوبى

ياااااااااااه
أكيد مش بالبساطة دي
لازم نعمل حسابنا إن في شهور 30 يوم وشهور 31 وشهر 28:D
ولأ وكمان أحيانًا فبراير بيبقه 29 يوم(لو السنة تقبل القسمة على 4):smoke:

أنا بعمل في البرنامج ده دلوقتى ولو خلصته أكيد هنزله


بس طبعًا بعد ما اسلمه للدكتور:P أصل السؤال اللي تحتيه مطلوب report ونفس الفكرة:hehehe:

[Yusuf]

كب بص بقى لو عرفت تعمل حسابك في الشهور ال 31 و ال 28 و ال 29 ابقى قولي بس هوا كده صح انا مجربة على اعياد ميلاد الناس اللي اعرفهم كلهم و جرب الكود و اعملة debug و دخل يوم عيد ميلادك بسنة 1991 او 1990 او 1992 على حسب و دخل نفس اليوم و الشهر و السنة دي 2010 و اقسم على 365 هيطلع 19 :P
و لو عاوز تعرف عندك كام سنة و شهر و يوم دلوقتي
دخل عيد ميلادك و تاريخ النهارده و اعمل الاتي
1- اقسم على 365 هيطلع السنين و جنبها كسر
2- اطرح رقم السنين
3- اضرب * 365
4- اقسم على 30 هيطلع عدد الشهور و جنبه كسر
5- اطرح عدد الشهور و سيب الكسر
6- اضربة في 30
7- يطلع عندك كام سنة و شهر و يوم :P
و شكرا على مشاركتك و انا بهزر معال في الايموشن ده :P :D:D:D:D ماشي :):):)

عادي أكيد مش هازعل :D


بالنسبة للبرنامج بقه:

اولاً: أنا بشتغل php ومتعود أحسب التواريخ كده (طبعًا هيه أسهل بكتير في ال php)
ثانيًا: جرب في البرنامج بتاعك تحط التاريخ الأول 29 12 2009 والتاني 1 1 2010 هتلاقي الناتج يومين مع إنهم تلاتة:smoke: ودي مشكلة كبيرة في البرنامج أي حد يلاحظها
ثالثًا: أكيد مش في أخر مسألة في الشيت (ومطلوبة report) ويكون الدكتور قاصد نحلها كده(إحنا في هندسة عين شمس) :petlya35ch:
رابعًا: أنا خلصت البرنامج (تقريبًا) ومرفق ال .exe بتاعه علشان تختبره:harhar:
وانت بتدخل التواريخ دخل اليوم مسافة الشهر مسافة السنة
أنا مظبت النسخة دي بحيث تقعد تعمل repeat علشان تكرر براحتك ومتفتحوش كل مرة:D
وطبعًا لو لقيت أي Bug، ياريت تقولي :D
وخد الموقع ده علشان تتاكد من عدد الأيام وأنت اللي بتدخل التواريخ :victory:

هوه المفروض أصلا مانزلش حلول أي ريبورتات لأنها المفروض بتتسلم للدكتور وناخد عليها بونص بس أنا وأنا بسلمه بكرة هاسأل الدكتور
ونصيحة بالمناسبة اللي عايز يعمل البرنامج ده بسرعة لازم يرسم ال flow chart

[Holmez]

بس هقولك حاجة خلى في أختيار عشان يقفل ال command list بدل ما هي شغاله الي ما لا نهاية
أنا قلتلك النسخة دي أنا عاملها تعيد علطول علشان كنت لسه بجرب كل الاحتمالات في البرنامج وفي الأخر هالغيها وأضيف حته الاختيار

انت سخنت ليه كدا يا حسان يا حبيبى :D
بصوا انتوا الاتنين محاضرة بكرة سودااااااا :P
نفضوا للكلام ده عشان الـ function حتبقى اكيد على اسئلة الـ arrays اللى المفروض خلصناها ,, فاكس حوار التاريخ ده دلوقتى :D

بالنسبة ل Q.4sheet 2
مش فاهمة الفكرة فى =
أصل لو التلاتة = فى نفس الوقت مش هيبقى فيه max.
ليه مش < وخلاص بدون =؟

هوا احنا بندور على max VALUE فمش فارقة لو دخل كل الارقام زى بعض
ساعتها ال VALUE حتبقى أى واحد فيهم .
