Task 1

Function: number × 10 display kare (sirf function likhna hai)

void timesTen(int number)
{
    cout << number * 10 << endl;
}

---

Task 2

1st Function: radius input le aur return kare
2nd Function: radius se area return kare

double getRadius()
{
    double r;
    cout << "Enter radius: ";
    cin >> r;
    return r;
}

double getArea(double radius)
{
    return 3.14159 * radius * radius;
}

Task 3

Even / Odd check (bool return)

bool isEven(int num)
{
    if (num % 2 == 0)
        return true;
    else
        return false;
}

Main ka example:

int n;
cin >> n;
if (isEven(n))
    cout << "Even";
else
    cout << "Odd";

Task 4

Two numbers add kar ke sum return

int add(int a, int b)
{
    return a + b;
}

Main ka example:

int x, y;
cin >> x >> y;
cout << "Sum = " << add(x, y);

Task 5

Three integers mein se largest return

int largest(int a, int b, int c)
{
    if (a > b && a > c)
        return a;
    else if (b > a && b > c)
        return b;
    else
        return c;
}

Task 6

Swap two numbers using function

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

Task 7

Uppercase → Lowercase (warna unchanged)

char toLower(char ch)
{
    if (ch >= 'A' && ch <= 'Z')
        return ch + 32;
    else
        return ch;
}

Task 8

Rectangle program with multiple functions

#include <iostream>
using namespace std;

double getLength()
{
    double l;
    cout << "Enter length: ";
    cin >> l;
    return l;
}

double getWidth()
{
    double w;
    cout << "Enter width: ";
    cin >> w;
    return w;
}

double getArea(double length, double width)
{
    return length * width;
}

void displayData(double length, double width, double area)
{
    cout << "Length = " << length << endl;
    cout << "Width  = " << width << endl;
    cout << "Area   = " << area << endl;
}

int main()
{
    double length = getLength();
    double width  = getWidth();
    double area   = getArea(length, width);
    displayData(length, width, area);

    return 0;
}
