 Write a program to read array of integers and print it in reverse order.

#include <stdio.h>

int main()

{

    // Initialize array

    int arr[] = {1, 2, 3, 4, 5};

    // Calculate length of array arr

    int length = sizeof(arr) / sizeof(arr[0]);

    printf("Original array: \n");

    for (int i = 0; i < length; i++)

    {

        printf("%d ", arr[i]);

    }

    printf("\n");

    printf("Array in reverse order: \n");

    // Loop through the array in reverse order

    for (int i = length - 1; i >= 0; i--)

    {

        printf("%d ", arr[i]);

    }

    return 0;

}

Write a program that adds two 1-dimensional array & store into third array.

#include <stdio.h>

int main()

{

    int arr1[5] = {1, 2, 3, 4, 5};

    int arr2[5] = {6, 7, 8, 9, 10};

    int result[5];

    int i;

    for (i = 0; i < 5; i++)

    {

        result[i] = arr1[i] + arr2[i];

    }

    printf("Resultant array after addition is:\n");

    for (i = 0; i < 5; i++)

    {

        printf("%d ", result[i]);

    }

    return 0;

}

Write a program to sort a given array in ascending order. (use Bubble Sort algorithm)

    #include <stdio.h>

void bubbleSort(int arr[], int n) {

    int i, j;

    for (i = 0; i < n-1; i++) {

        for (j = 0; j < n-i-1; j++) {

            if (arr[j] > arr[j+1]) {

                // swap arr[j] and arr[j+1]

                int temp = arr[j];

                arr[j] = arr[j+1];

                arr[j+1] = temp;

            }

        }

    }

}

int main() {

    int arr[] = {5, 2, 9, 1, 5, 6};

    int n = sizeof(arr)/sizeof(arr[0]);

    int i;

    printf("Before sorting: ");

    for (i = 0; i < n; i++) {

        printf("%d ", arr[i]);

    }

    bubbleSort(arr, n);

    printf("\nAfter sorting: ");

    for (i = 0; i < n; i++) {

        printf("%d ", arr[i]);

    }

    return 0;

}
