المشاركة الأصلية كتبت بواسطة رغـــدهـ ~ انا عندي سؤال بالنسبه الى loop وانوعهآ الثلاثه انا فاهمه فكرتهم الاسآسيه بس السؤال اذا جيت احل كيف ارتب افكاري واحله بطريقه صح وش الاشياء اللي لازم اسويها قبل كل شي وكذا

اول شي لازم تتدربي على طريقه كتابه كود اللوب و تحفظيها تمام 100 %
ثاني شي تحددي هل هي for أو while أو do while
ثالث شي اذا كانت for تنتبهي لعدد اللوبات و تنتبهي للشرط جيدا يعني >= مو زي > تختلف كتير و في الحل تختلف
و تنتبهي للقيمه يلي ساوا فيها هل هي 0 او 1 او اي رقم مثلا :
اذا كانت اللوب زي كدا for (int i = 0; i<= 5;i++ ) //for loop
في هذي الحاله يكون عدد اللوبات 6 لانو بدا من الصفر الى 5 اما اذا كان الشرط >5 راح يكون عدد اللوبات 5 بس هذا الشي كتير الطلاب يلخبطوا فيه في الاختبارات

و بالنسبه للوب داخل اللوب يعني مثلا :

for (i = 1; i <= 2; i++)// loop1
for (j = 1; j <= 3; j++)// loop 2
printf("*"); //star

هنا راح يطبع 6 نجوم يلي هييا عدد اللوبات في اللوب الاولى ضرب عدد اللوبات في اللوب الثانيه = 6 و لا نعتمد على الارقام المكتوبه لازم نحسب اللوبات بنفسنا يعني مو 3 * 2=6 و خلاص لا لازم ننتبه للشروط كويس

مثال 3*2 هدي بتحسبها على عدد اللوب مو على الرقم المكتوب لانو احيانا يعطي قيمه ال i 0 و احيانا 1 يعني في المثال يلي فوق اعطاها 1 فتطلع قيمه اللوب الاولى 2 و الثانيه 3 اما اذا اعطاها قيمه 0 راح يبدا من الصفر فتطلع قيمه اللوب الاولى 3 و الثانيه 4 ولازم تنتبه للشرط هل هو >= أو فقط > لانها تفرق كتير
الخلاصه
لازم تحسب كم لوب في كل وحده و ما تعتمد على الارقام المكتوبه ركزوا

أما while loop و do while هدي سهله مجرد لوب عاديه اذا حقق الشرط يدخل و ينفذ و اذا ما حققوا ما يدخل اللوب
بس الفرق انو do while يدخل في اللوب و ينفذها مره وحده على الاقل بعدين يتحقق من الشرط أما ال while يتحقق من الشرط بعدين يدخل في اللوب اذا حقق الشرط
و بس

تقدر تضيف else if و تحط شرطها انو يكون المدخل اقل من 1 و اكثر من 4 و يطبعلو error
يعني تحط هذا الشرط
else if (char>4 || char<1) // 1
printf ("error you enter num out of range 1-4")//2

و عشان تخليه لووب تحط البرنامج حقك في لووب while
و بس

بالنسبه للبروجكت هذا لازم تسويلو 3 كلاسات و تحط الاوامر المطلوبه في البرنامج لكل كلاس مثل ال set & get

و بعدين تسوي ال main و تستدعيهم على حسب مو طالب البرنامج

الله يسعدكككم ساعدوني في هالبورجيكت بوكرا عندي اختبار نهائي حاولت احلو بس م عرفت =(((

Project 5 Deion:
In this project, you will modify the Cargo Charges program you have written in Project 4 (See attached). You need to implement the following extensions:
Extension 5: The program should allow the user to make at least two shipments for each category. The charges of these shipments will be stored in arrays (e.g. array SaudiaCharges() will contain the charges for the shipments made for Saudi Arabia, . array GulfCharges() will contain the charges for the shipments made for Gulf and array OtherCountryCharges() will contain the charges for the shipments made for other countries).
Array Contents after the sample run 1:
SaudiaCharges() Array:



4275 5700 … … … … … …


GulfCharges() Array:




1308.15 3197.70 571.2 … … … … …





OtherCountryCharges() Array:




7481.25 1571.0625 … … … … … …

Then the relevant methods will find the maximum charges from all the charges for shipments made for Saudia, Gulf and other countries. For example, the method Saudia() will find the maximum charges from all the shipments made for Saudi Arabia, the method Gulf() will find the maximum charges from all the shipments made for Gulf and the method OtherCountries() will find the maximum charges from all the shipments made for other countries. Finally the program will display the maximum of these three charges.

Extension 1:If, the user entersS or s (for shipping in Saudi Arabia) ,G or g (for shipping to Gulf countries) , O or o (for shipping to other countries), the program should call the corresponding methods for performing all the previous tasks for these countries. For example, if the user enters S or s, the main() method should call a method Saudia(). In Saudia() method, the user will enter a value for cargo weight and the distance, and calculate the charges according to table 1 (as you did in project 3).
If the user enters G or g, the main() method should call a method Gulf(). In Gulf() method, the user will enter a value for cargo weight and the distance, and calculate the charges according to table 1 (as you did in project 3).
If the user enters ) O or o, the main() method should call a method OtherCountries(). In OtherCountries() method, the user will enter a value for cargo weight and the distance, and calculate the charges according to table 1 (as you did in project 3).
After each program run you need to ask the user if he wants to ship another cargo (using confirmation dialog of JOptionPane). If the user clicks YES, the program will continue and ask the user to input the new cargo details. This process continues until the user clicks NO.



Extension 2:
The program must keep a count of the number of shipments the user wants to ship and print the count number after the user clicks NO. For example, if the user has shipped the 4cargoes , then the program should print: "You have used the program 4 times".
Extension 3:The program should calculate and print the shipping charges and discount for each region (Saudi Arabia, Gulf countries and other countries) in the methods Saudia(), Gulf() and OtherCountires() respectively, after each cargo shipment .
At the end the program will print the total charge for all cargoes by using the method TotalCharges() which will return the total charges for all cargoes to main() method where it will be displayed.
Extension 4: The program will terminate only if two valid shipments for any of the category (i.e. Saudia, Gulf or Other countries) is made. Otherwise, it will continue to run (asking the user for input and repeating the whole program from extension 1).














Attachment: (Project 4)
Project 2 Deion:
A Shipping Company charges cargoes in Saudi Arabia based on the following rates :

Weight of the Cargo (in KG) Shipping Rate per KM
2 kg or less SR 0.25
Over 2 kg, but not more than 10 kg SR 0.2
Over 10 kg, but not more than 20 kg SR 0.15
Over 20 kg, but not more than 50 kg SR 0.2
table 1
Shipping charges for the Gulf countries costs 2% more and 5% more for other countries.
write a Java program that allows the user to enter the weight of the cargo , the place and
the distance it is to be shipped(Saudi Arabia, Gulf country or other) and then displays the charges.

Input validation:
The user has to enter S (for shipping in Saudi Arabia) ,G (for shipping to Gulf countries) , O (for shipping to other countries). Next, the user will enter a value cargo weight and the distance . The program will calculate the charges according to table 1. The output of the program should be the shipping charges. In addition, consider the following scenarios in the output:
1. If the user inputs a character that is not recognized (NOT S, G, orO), then the program prints “Wrong Selection!”, and exits.
2. If the user inputs 0 or less for the value of the cargo weight , the program will display a message that states “the weight must be larger than Zero!”
3. The maximum weight the companywill ship is 50 KG, So if the user enter more than 50 KG, the program will display “the weight must not exceed 50KG!”
4. These are the company’s minimum and maximum shipping distances. So your program should not accept distances of less than 10 Km or more than 5000 KM. Display an appropriate message to the user if entered unaccepted distance.
5. After displaying the shipping charge,the program should also display the discount for the charges value according to the following rules:
a. If charges value is less than or equalSR 1000, print “Discount is 0 %.”
b. If charges value is less than 10000, print “Discount is 5%.”
c. If charges value is greater than or equal 10000, print “Discount is 10%.”


Project 3 Deion:
In this project, you will modify the Cargo Charges program you have written in Project 2 (See attached). You need to implement the following extensions:
Extension 1: After each program run you need to ask the user if he wants to ship another cargo (using confirmation dialog of JOptionPane). If the user clicks YES, the program will continue and ask the user to input the new cargo details. This process continues until the user clicks NO.
Extension 2:The program must keep a count of the number of shipments the user want to ship and print the count number after the user clicks NO. For example, if the user has shipped the 4cargoes , then the program should print: "You have used the program 4 times".
Extension 3:The program should calculate and print the shipping charges and discount for each region (Saudi Arabia, Gulf countries and other countries) after each cargo shipment . At the end the program will print the total charge for all cargoes.
Extension 4: The program will terminate only if one valid shipment is made. Otherwise, it will continue to run (asking the user for input and repeating the whole program from extension 1).
