Print K th left rotation of array elements

Here given code implementation process.

// C Program
// Print K th left rotation of array elements
#include <stdio.h>

// Display array elements
void display(int arr[], int size)
{
	printf("\n Array Elements \n");
	for (int i = 0; i < size; ++i)
	{
		printf("   %d", arr[i]);
	}
	printf("\n");
}
// Prints the left k rotation of an array
void leftRoationByK(int arr[], int size, int k)
{
	display(arr, size);
	printf(" Rotated left by %d element \n", k);
	int j = k % size;
	for (int i = 0; i < size; ++i)
	{
		// display element
		printf("   %d", arr[(j + i) % (size)]);
	}
}
int main()
{
	// Define array of integer elements
	int arr1[] = {
		8 , 3 , 1 , 6 , 5 , 4 , 2 , 7 , 9
	};
	int arr2[] = {
		1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10
	};
	// Get the size
	int size = sizeof(arr1) / sizeof(arr1[0]);
	// Test Case A (of arr1)
	leftRoationByK(arr1, size, 2);
	leftRoationByK(arr1, size, 3);
	// Get the size
	size = sizeof(arr2) / sizeof(arr2[0]);
	// Test Case B (of arr2)
	leftRoationByK(arr2, size, 4);
	leftRoationByK(arr2, size, 13);
