Cyclically rotate an array by one in C

Problem statement: Cyclically rotate an array by one in C

Store the last element in a temp variable.
Traverse and Shift all elements one by one by a position ahead.
Replace the first element of the array with the temp variable.

//Cyclically rotate an array by one in C
#include <stdio.h>

/*----Function to rotate an array cyclyically by one ----*/
void rotateByOne(int arr[], int n)
{
   int temp = arr[n - 1], i;
   for (i = n - 1; i > 0; i--)
      arr[i] = arr[i - 1];
   arr[0] = temp;
}

void printArray(int arr[], int n)
{
   for (int i = 0; i < n; i++)
      printf("%d\t", arr[i]);
}

int main()
{
   int n;
   printf("Enter the number of element\t");
   scanf("%d", &n);
   int arr[n];
   printf("Enter array elements\n");
   for (int i = 0; i < n; i++)
      scanf("%d", &arr[i]);
   printf("Array elements are:\n");
   printArray(arr, n);
   rotateByOne(arr, n);
   printf("\nArray elements after rotation:\n");
   printArray(arr, n);
