c program to print array elements using recursion code example

Example: c program to print array elements using recursion

/**
 * C program to print array elements using recursion.
 */

#include <stdio.h>
#define MAX_SIZE 100

/* Function declaration */
void printArray(int arr[], int start, int len);


int main()
{
    int arr[MAX_SIZE];
    int N, i;
    
    /* Input size and elements in array */
    printf("Enter size of the array: ");
    scanf("%d", &N);
    printf("Enter elements in the array: ");
    for(i=0; i<N; i++) 
    {
        scanf("%d", &arr[i]);
    }
        
    /* Prints array recursively */
    printf("Elements in the array: ");
    printArray(arr, 0, N);
    
    return 0;
}


/**
 * Prints an array recursively within a given range.
 */
void printArray(int arr[], int start, int len)
{
    /* Recursion base condition */
    if(start >= len)
        return;
        
    /* Prints the current array element */
    printf("%d, ", arr[start]);
    
    /* Recursively call printArray to print next element in the array */
    printArray(arr, start + 1, len);
