1. Six Employees ke Working Hours (Array)

#include <iostream>
using namespace std;

int main() {
    int hours[6];

    for(int i = 0; i < 6; i++) {
        cout << "Enter hours worked by employee " << i+1 << ": ";
        cin >> hours[i];
    }

    cout << "\nHours Worked:\n";
    for(int i = 0; i < 6; i++) {
        cout << "Employee " << i+1 << ": " << hours[i] << endl;
    }

    return 0;
}

2. 10 Integers lo aur ≥10 count karo

#include <iostream>
using namespace std;

int main() {
    int arr[10], count = 0;

    for(int i = 0; i < 10; i++) {
        cout << "Enter number " << i+1 << ": ";
        cin >> arr[i];
        if(arr[i] >= 10)
            count++;
    }

    cout << "Numbers greater than or equal to 10: " << count << endl;

    return 0;
}

3. First aur Last Element Swap (1-D Array)

#include <iostream>
using namespace std;

int main() {
    int arr[5] = {10, 20, 30, 40, 50};
    int temp;

    temp = arr[0];
    arr[0] = arr[4];
    arr[4] = temp;

    cout << "Array after swapping:\n";
    for(int i = 0; i < 5; i++) {
        cout << arr[i] << " ";
    }

    return 0;
}

4. Two Matrices ka Multiplication (Function)

#include <iostream>
using namespace std;

void multiply(int a[2][2], int b[2][2]) {
    int c[2][2] = {0};

    for(int i = 0; i < 2; i++) {
        for(int j = 0; j < 2; j++) {
            for(int k = 0; k < 2; k++) {
                c[i][j] += a[i][k] * b[k][j];
            }
        }
    }

    cout << "Result Matrix:\n";
    for(int i = 0; i < 2; i++) {
        for(int j = 0; j < 2; j++) {
            cout << c[i][j] << " ";
        }
        cout << endl;
    }
}

int main() {
    int a[2][2] = {{1,2},{3,4}};
    int b[2][2] = {{5,6},{7,8}};

    multiply(a, b);

    return 0;
}

    int c[2][2];

    for(int i = 0; i < 2; i++) {
        for(int j = 0; j < 2; j++) {
            c[i][j] = a[i][j] + b[i][j];
        }
    }

    cout << "Sum Matrix:\n";
    for(int i = 0; i < 2; i++) {
        for(int j = 0; j < 2; j++) {
            cout << c[i][j] << " ";
        }
        cout << endl;
    }
}

    int b[2][2] = {{5,6},{7,8}};

    add(a, b);

    return 0;
}

#include <iostream>
using namespace std;

int main() {
    int a[2][3] = {{1,2,3},{4,5,6}};
    int t[3][2];

    for(int i = 0; i < 2; i++) {
        for(int j = 0; j < 3; j++) {
            t[j][i] = a[i][j];
        }
    }

    cout << "Transpose Matrix:\n";
    for(int i = 0; i < 3; i++) {
        for(int j = 0; j < 2; j++) {
            cout << t[i][j] << " ";
