C Exercises: Rotate the elements of a given array of integers in left direction and return the new array

C-programming basic algorithm: Exercise-37 with Solution

Write a C program to rotate the elements of a given array of integers (length 4 )in left direction and return the new array.

C Code:

#include <stdio.h>
#include <stdlib.h>
int main(void){ 
    int arr_size;
    int a1[] = {10, 20, 30, 40};
    arr_size = sizeof(a1)/sizeof(a1[0]);
    printf("Elements in original array are: ");  
    print_array(a1, arr_size);
    int result[] = { a1[1], a1[2], a1[3], a1[0] };
    arr_size = sizeof(result)/sizeof(result[0]);
    printf("\nElements in new array are: ");  
    print_array(result, arr_size);
    }     
 print_array(int parray[], int size)
  {
   int i;      
   for( i=0; i<size-1; i++)  
    {  
        printf("%d, ", parray[i]);  
    } 
   printf("%d ", parray[i]);  
   printf("\n");   
  }

Sample Output:

Elements in original array are: 10, 20, 30, 40 

Elements in new array are: 20, 30, 40, 10
