(Q.3-1) Write a function that swaps the kth and (k+1)th elements in an integer array

#include<stdio.h>
void swapping(int arr[],int n,int k)
{
    int temp;

    temp=arr[k-1];
    arr[k-1]=arr[k];
    arr[k]=temp;

    printf("\n\nAfter swapping:\n%dth element is: %d\n%dth element is: %d",k,arr[k-1],k+1,arr[k]);

}
int main()
{
    int n;
    printf("Enter the value of n: ");
    scanf("%d",&n);

    int arr[n];
    printf("Enter the array elements: ");

    for(int i=0;i<n;i++)
    {
        scanf("%d",&arr[i]);
    }

    int k;
    printf("Enter the position: ");
    scanf("%d",&k);

    printf("Before swapping:\n%dth element is: %d\n%dth element is: %d",k,arr[k-1],k+1,arr[k]);
    swapping(arr,n,k);
    return 0;
}
