السلام عليكم ورحمة الله وبركاته
اشكرك اخوي على جهدك في هذا الموضوع
ويعطيك الله الف عافية
انا احتاج مساعدة منك اخوي في برنامج ما قدرت احل جزئية منه
البرنامج المطلوب :

you are asked to make a bubble sort program to sort an array of random integers (the random number has range from 1->100000) , you will test the sorting program for different array size(10,100,1000,10000,100000,1m,10m) and you will calculate the consumed time in sorting the array in each case , then you will make a chart between the number of elements in array and the consumed time in sorting
also you will do this task for insertion sort and compare between the two algorithms

اما الحل اللي قدرت اوصله لحد الان موجود في الرابط والشي الوحيد الي ماني عارف اشغله هو التوقيت وحساب الفرق ومشكلة عمل مصفوفة اراي راندوم(عشوائي) من اكثر من مليون
فاتمنى تساعدني واكون لك من الشاكرين وادعيلك انشالله

شكرا على الخدمه..... عهندي مشكله في قراءة الرسائل المرسله بالايميل باللغه العربيه .... اريد برنامج يحل المشكله... و مشكوووووووووووووووووووووور

[Uchiha.Haibra]

اخوي هالبرنامج من اسهل البرامج اللي تقدر تسويها :

#include <conio.h>
#include <iostream>
 
using namespace std;
 
 
int main()
{
    float height;
    float width;
    float result;
 
    cout << "Please enter the height: ";
    cin >> height;
 
    cout << endl;
 
    cout << "Please enter the width: ";
    cin >> width;
 
      result = height * width;
    cout << "The area is: " << result;
 
    getch();
    return 0;
}

مشكور اخوي,, بس ممكن اعرف كيف احول الكود إلى برنامج
فكرة المستطيلات جميلة

[علي جنيدي]

أعتذر من الأخ Agent 47 ليس لدي وقت لأصلح الحاسب ولكن عدي فكرة وهي خذ الوقت في بداية الحلقة ثم في نهايتها واطرح الوقتين

السلام عليكم
ممكن يا اخويه علي اتساعدني في حل البرنامج انا برسل لك السؤال و حلي للبرنامج في أخطاء كثيره و خاصه في موضوع ال protected ماعرف كيف اسويلهم define
اتمنى اتساعدني لانه احتاجه يوم الأحد و سألت كثير ناس محد راضي يساعدني ف أنت الحين اخر ملجأ لي

الواجب في الملف المرفق

انا فكرت لو اطرشلك البرنامج اللي سويته عالايميل احسن عشان تقدر تفتحه دايركت من البرنامج لاني اهني احسه يطلع املخبط و البرنامج طويل اذا حبيت تقدر اطرشلي ايميلك عالخاص و بطرشلك الكود

المهم اذا هو حلي هو عبار عن project فيه أخطاء كثيره اغلبها في ال defining

Developing secret codes has interested people for centuries. A simple coding scheme can be developed by replacing each character in a text file by another character that is a fixed number of positions away in the collating sequence. For example, if each character is replaced by the character that is two characters to its right in the alphabet, then the letter ‘a’ is replaced by the letter ‘c’, the letter ‘b’ is replaced by the letter ‘d’ and so on.



Write a menu driven providing the following options:



1) Code a file


2) Decode file


3) Display file


4) Exit



Each menu item would correspond to one of the following tasks:



(1) Reads the text in a file and then generates a new file that contains the coded text using the above scheme (Change only the alphanumeric characters).



(2) Decodes the file using the same scheme presented in step (1) (Test the program by using the files generate by step (1) above).



(3) Allows the user to display the content of a specific file on the screen. Name of to display file should be provided by user.



(4) Exit the program.



Name your files as follows:


1) Original.txt: Input text file to be decoded.


2) Coded.txt: Coded file


3) Decoded.txt: Decoded file


Note that when you code and decode a file the resulting decoded file should match the original file

الأخ الكريم علي الجنيدي

عندي برنامج أريد برمجته على البورلاند هكذا طلب منا

بحيث يطلب من المستخدم أن يدخل اي جملة تحتوي على كلمتي END+BEGIN

ثم يخرج الجملة التي بينهما

هل من الممكن مساعدتي في إيجاد كود صالح ؟!!

[ragazzo]

اخي العزيز ارجو مساعدتي في حل السؤالين !

ولك جزيل الشكرا مع الاخلاص

1( Write a C++ program which will produce the perfect numbers between 1 and 1000.
A perfect number is defined to be equal to the sum of its perfect divisors. For example, 28 is a perfect number, since 28 = 1 + 2 + 4 + 7 + 14 where 1, 2, 4, 7, 14
are the perfect divisors of 28

2(

Write a C++ program that simulates the rolling of two dice. The program should use rand() function to roll the first die, and should use rand() function again to roll the second die. The sum of the two values should then be calculated. Note: Since each die can show an integer value from 1 to 6, then the sum of the two values will vary from 2 to 12 with 7 being the most frequent sum and 2 and 12 being the least frequent sums. The table below shows the 36 possible combinations of the two dice. Your program should roll the two dice 36,000 times. Use counters to store the numbers of times each possible sum appears. Print the results in a tabular format. Also determine if the totals are reasonable, i.e., there are six ways to roll a 7, so approximately one sixth of all the rolls should be 7 ( Make sure to include <stdlib.h> and <time.h> libraries and use the switch statement. )


في انتظار حلك اخوي ومشكوور !

أتمنى اخوي تحل سؤال جزيرة الواك واك

بسرعة خلال هذا اليوم..واضع نفس سؤالي

وربي بسرعة

[Breaking Heart]

لو سمحت ممكن تحل لي السؤالين هذي :

Exercise # 1
The following class deal with Student information.

// Student information class
..
..
enum status{regular, dropped, excused, unspecified};
class student_recored{
string name;
long ID;
float GPA;
status student_status;
public:
student_record(string n, long id)
{
new_student(n,id);
}
void new_student(string, long);
float retrieve_GPA(long);
status get_status(long);
status set_status(long);
void print_students( );
……
};
int main()
{
……
student_record studen1("Lima Fahad", 42410), student2, student3;
student.new_student("Mona Saad", 42401);
…….
return 0;
}



- You should add 10 new student and maintain their information which name, id, status.
- You also should define a function that called SearchId which search for a target ID in all your students list.
- This program should contain a menu for choose which one of these two function like this menu

*******************

….Welcome To Student Program…

Choose one of the following :-
1- Add students.
2- Print the GPA for all students.
3- Print all Students Information.
4- Exit …

********************

Exercise # 2
Problem about Random Number Generation.
Write a program that deal with two function

- First function TenRandNum use for print ten real random number. Note: use rand() function.

- Second function GuessNum that contain two variables one as iGuess that refer to the number that get form the user, and iSecret that refer to the random number. This function should compare between these two variables and display if that the iGuess identical to iSecret or higher or lower, as the following output.


Guess the number (1 to 10): 5The secret number is higherGuess the number (1 to 10): 8The secret number is lowerGuess the number (1 to 10): 7Congratulations!

- This program should contain a menu for choose which one of these two function like this menu

*******************
Choose one of the following :-
1- print ten ramdom number.
2- Guess the number
3- Exit.
