Write a c program to make a circular rotation of an array by k positions using the loops

Write a c program to make a circular rotation of an array by k positions using the loops. In this program, you will learn how to make a circular rotation of an array by k positions using the loops.

Take an example to make this circular rotation through a c program:

// Write a c program to make a circular rotation
// of an array by k positions using the loops
#include <stdio.h>
#define N 100

int main()
{
    int e, r, d;
    int arru[N];
    // e is the number of array elements
    // r is the number of rotations of the array
    // d is the number of indexes to display
    // arru is the array container

    printf("-----Enter the number of elements of the array-----\n");
    scanf("%d", &e);

    printf("\n-----Enter the number of rotations of the array-----\n");
    scanf("%d", &r);

    printf("\n-----Enter the number of indexes to be displayed-----\n");
    scanf("%d", &d);

    printf("\n-----Input the array elements-----\n");
    for (int i = 0; i < e; i++)
    {
        scanf("%d", &arru[i]);
    }

    printf("\n\n------The Array Elements are------\n");
    for (int i = 0; i < e; i++)
    {
        printf("%d ", arru[i]);
    }
    printf("\n");

    // Remove the number of full array rotations from k
    r %= e;

    for (int i = 0; i < d; i++)
    {
        int in;
        printf("\n------Enter the index of the array to be displayed------\n");
        scanf("%d", &in);

        printf("\n------The element in the array is------\n");

        // Calculate the new index
        printf("%d\n", arru[(e + in - r) % e]);
    }

    return 0;
}
