Q48: Write C++ code to determine the size of various data type on a computer.
(use character and double only).

#include <iostream> 
using namespace std;

int main()
{
char character;
double doubleonly;

cout << "Size of int: " << sizeof(character) << " bytes" << endl;
cout << "Size of float: " << sizeof(doubleonly) << " bytes" << endl;

return 0;
}
Q49: Consider two integer numbers U=15 and V=8.
C++ program to implement the following operator description.
1- Checks if the values of two operands are equal or not.
2- Checks if the value of left operand is greater than or equal to the value of right operand.

#include <iostream> 
using namespace std;

int main()
{
int U = 15, V = 8;
bool areEqual = (U == V);
bool isGreaterOrEqual = ( U >= V);

cout << "Are the values of U and V equal? " << areEqual << endl;
cout << "Is U greater than or equal to V? " << isGreaterOrEqual << endl;

return 0;
}

Q50: Write a C++ program to print the sequence of numbers (95-105), except number 101. The code should has continue statement.

#include <iostream> 
using namespace std;

int main()
{
for ( int i = 95; i <= 105; i++)
{
if ( i == 101)
{
continue;
}
cout<<i<<", ";
}
cout<<endl;

return 0;
}


اذا طلبه :
use do while loop

#include <iostream> 
using namespace std;
int main ()
{
int a = 95;
do
{
if( a == 101)
{
a = a + 1;
continue;
}
cout <<a<<", ";
a = a + 1;
}
while( a <= 105);
return 0;
}

#include <iostream> 

using namespace std;

int main()
{
int a , fac;
cout << "enter the number (a) : ";
cin >> a;
fac = 1;
for ( int i =1; i <= a ; i++)
{
fac = fac * i;
}
cout << "the fac of the entered number is : "<<fac<<endl;
// or write ( cout << " the fac of the entered number is \n" ;
return 0;
}
Q6/
Write C++ code to swap two integer number (use appropriate function).

So/

بالتأكيد، إليك كود C++ يستخدم وظيفة لتبديل قيمتين صحيحتين، ويستخدم iostream و using namespace std فقط:

#include <iostream>

using namespace std;

// وظيفة لتبديل قيمتين
void swapNumbers(int &num1, int &num2) {
int temp = num1;
num1 = num2;
num2 = temp;
}

int main() {
int number1, number2;

// الحصول على إدخال المستخدم
cout << "Enter the first number: ";
cin >> number1;

cout << "Enter the second number: ";
cin >> number2;

// استخدام الوظيفة لتبديل الأرقام
swapNumbers(number1, number2);

// عرض النتيجة
cout << "After swapping, the numbers are: " << number1 << " and " << number2 << endl;

return 0;
}
هذا الكود يستخدم iostream و using namespace std ويحتوي على وظيفة swapNumbers لتبديل قيمتين.

Q2/
Write C++ code to find the Factorial for any integer number (use appropriate function).

So/
#include <iostream>
using namespace std;

// Function to calculate factorial recursively
int factorial(int n) {
if (n == 0 || n == 1) {
return 1;
} else {
return n * factorial(n - 1);
}
}

int main() {
int number;

// Input the number from the user
cout << "Enter a non-negative integer number: ";
cin >> number;

// Calculate and display the factorial of the number
cout << "Factorial of " << number << " is: " << factorial(number) << endl;

return 0;
}
Q51: Write a function which, given an array of integers, returns the integer that appears most frequently in the array.
E.g. for the array [ 1 2 3 2 3 4 2 5 ] your function should return 2.


#include <iostream> 
using namespace std;

int mostFrequent(const int arr[], int size)
{
int mostFrequentNum = arr[0];
int maxFrequency = 1;

for (int i = 0; i < size; ++i)
{
int currentNum = arr[i];
int currentFrequency = 1;

for (int j = i + 1; j < size; ++j)
{
if (arr[j] == currentNum)
{
currentFrequency++;
}
}

if (currentFrequency > maxFrequency)
{
mostFrequentNum = currentNum;
maxFrequency = currentFrequency;
}
}

return mostFrequentNum;
}

int main()
{
int numbers[] = {1, 2, 3, 2, 3, 4, 2, 5};
int size = sizeof(numbers) / sizeof(numbers[0]);

int result = mostFrequent(numbers, size);

cout << "The most frequent number is: " << result << endl;

return 0;
}

Q52: Write the function sum() with four parameters that calculates the arguments provided and returns their sum. Parameters: Four variables of type long.
Returns: The sum of type long.
Use the default argument 0 to declare the last two parameter of the function sum().
Test the function sum() by calling it by all three possible methods.
Use random integers as arguments.


#include <iostream>
using namespace std;

// دالة لحساب مجموع أربعة متغيرات من نوع long
long sum(long a, long b, long c = 0, long d = 0) {
return a + b + c + d;
}

int main() {
// تعيين أرقام ثابتة للاختبار
long num1 = 10;
long num2 = 20;
long num3 = 30;
long num4 = 40;

// طريقة 1: استدعاء دالة sum() مع أربع متغيرات
long result1 = sum(num1, num2, num3, num4);
cout << "Method 1: Sum of " << num1 << ", " << num2 << ", " << num3 << ", " << num4 << " is: " << result1 << endl;

// طريقة 2: استدعاء دالة sum() مع ثلاث متغيرات
long result2 = sum(num1, num2, num3);
cout << "Method 2: Sum of " << num1 << ", " << num2 << ", " << num3 << " is: " << result2 << endl;

// طريقة 3: استدعاء دالة sum() مع متغيرين
long result3 = sum(num1, num2);
cout << "Method 3: Sum of " << num1 << ", " << num2 << " is: " << result3 << endl;

return 0;

تغيير قيمة المعاملات باستخدام البوينتر :
#include <iostream>
using namespace std;

int p ( int *ptr){
*ptr+= 1;
return *ptr;
}
int main() {
int m = 5;

cout << p(&m) << endl;
cout << m << endl;
cout << p(&m) << endl;
}
اظهار عنصر معين من المصفوفة باستخدام البوينتر :
#include <iostream>
using namespace std;

int main() {
int arr[] = {5, 7, 9};

cout << *(arr+2) << endl;
}
طباعة مصفوفة باستخدام البوينتر :
#include <iostream>
using namespace std;

int main() {
int arr[5] = {3, 5 , 7, 9, 11};

for (int i = 0; i < 5; i++){
cout << *(arr+i) << ", ";
}
cout<<endl;
}
سواب بالبوينتر :
#include <iostream>
using namespace std;

void first(int *a, int *b){
int temp;
temp = *a;
*a = *b;
*b = temp;
}

int main()
{
int m = 5, n = 3;
first(&m, &n);

cout << m << ", "<< n <<endl;

return 0;
}
سواب بالرفرنس :
#include <iostream>
using namespace std;

void first(int &a, int &b){
int temp;
temp = a;
a = b;
b = temp;
}

int main()
{
int m = 5, n = 3;
first(m,n);

cout << m << ", "<< n <<endl;

return 0;
}
سواب بالستركت :
#include <iostream>
using namespace std;

struct numb {
int a, b;
};
void swapp(numb &num) {
int temp;
temp = num.a;
num.a = num.b;
num.b = temp;
}

int main() {
numb num ={9 ,5};
swapp(num);
cout << num.a << ", " << num.b << endl;
}
ارسال قيم للفنكشن باستخدام Array و بوينتر :
#include <iostream>
using namespace std;

int* Arr(int rar[3]) {
for (int i = 0; i < 3; ++i) {
cout << rar[i] <<", ";
}
cout<<endl;
return rar;
}

int main() {
int A[3] = {5, 3, 8};
int* rar = Arr(A);
return 0;
}
declare a struct called personweight with a member variables name and weight. the struct should have an implementation to print a message " person-name you are overweight " if the person's weight is over 75kg, otherwise print a message " person-name you are fit ".

#include <iostream>
using namespace std;

struct personweight {
string name;
float weight;

void printStatus() {
if (weight > 75) {
cout << name << " you are overweight" << endl;
} else {
cout << name << " you are fit" << endl;
}
}
};

int main() {
personweight person1;
person1.name = "John";
person1.weight = 80;

personweight person2;
person2.name = "Alice";
person2.weight = 70;

person1.printStatus();
person2.printStatus();

return 0;
}

تكدر تستبدل التعريف الي بالmain بهذا
personweight person1 = {"Alice", 70};

personweight person2 = {"John", 80};

هنا اول شيء فتحنا كلاس بأسم bank
و سويناه public
public :
لان اي شيء بداخل الكلاس يعتبر شيء خاص ممنوع الوصول له ف نكتب public حتى نكدر نستخرج هاي المتغيرات بالmain براحتنا و نستدعيها

و كتبنه المتغيرات الي رادهن ثلاث متغيرات
اسم الحساب AccountHolder ( نوع سترنغ )
رقم الحساب AccountNumber ( نوع انتجر )
الفلوس الي بالحساب balance ( نوع دوبل )
