Print array elements using recursion

Problem statement:- Program to print array elements using recursion.

Data requirement:-

   Input Data:-n, arr

  Output Data:-arr

Program in C

Here is the source code of the C Program to print array elements using recursion.

Code:

#include<stdio.h>

void PrintArray(int arr[], int i, int n)

{

    if(i>=n)

        return;

    printf("%d ",arr[i]);

    PrintArray(arr,i+1,n);

}

int main()

{

    int n,i;

    printf("Enter your array size:");

    scanf("%d",&n);

    int arr[n];

    printf("Enter the Array Element:");

    for(i=0;i<n;i++)

    {

        scanf("%d",&arr[i]);

    }

    printf("Array Element Are:");

    PrintArray(arr,0,n);

}

Input/Output:

Enter your array size:5

Enter the Array Element:4 8 10 3 5

Array Element Are:4 8 10 3 5

Program in C++

Here is the source code of the C++ Program to print array elements using recursion.

Code:

#include<iostream>

using namespace std;

void PrintArray(int arr[], int i, int n)

{

    if(i>=n)

        return;

    cout<<arr[i]<<" ";

    PrintArray(arr,i+1,n);

}

int main()

{

    int n,i;

    cout<<"Enter your array size:";

    cin>>n;

    int arr[n];

    cout<<"Enter the Array Element:";

    for(i=0;i<n;i++)

    {

        cin>>arr[i];

    }

    cout<<"Array Element Are:";

    PrintArray(arr,0,n);

}

Input/Output:

Enter your array size:6

Enter the Array Element:9 13 55 65 100 2

Array Element Are:9 13 55 65 100 2

Program in Java

Here is the source code of the Java Program to print array elements using recursion.

Code:

import java.util.Scanner;

public class PrintArrayElement {

static void PrintArray(int arr[], int i, int n)

{

if(i>=n)

return;

System.out.print(arr[i]+" ");

PrintArray(arr,i+1,n);

}

public static void main(String[] args) {

Scanner cs=new Scanner(System.in);

int n,i;

System.out.println("Enter your Array Size:");

n=cs.nextInt();

int arr[]=new int[n];

System.out.println("Enter the Array Element:");

for(i=0;i<n;i++)

{

arr[i]=cs.nextInt();

}

System.out.print("Array Element Are:");

PrintArray(arr,0,n);

cs.close();

}

}

Input/Output:

Enter your Array Size:

9

Enter the Array Element:

7 3 5 6 500 6 9 2 1

Array Element Are:7 3 5 6 500 6 9 2 1 

Program in Python

Here is the source code of the Python program to print array elements using recursion.

Code:

def PrintArray(arr,i,n):

    if(i>=n):

        return

    print(arr[i],end=" ")

    PrintArray(arr,i+1,n)

arr=[]

n = int(input("Enter the size of the array: "))

print("Enter the Element of the array:")

for i in range(0,n):

    num = int(input())

    arr.append(num)

print("Array Element Are:")

PrintArray(arr,0,n)

Input/Output:

Enter the size of the array: 3

Enter the Element of the array:

4

10

8

Array Element Are:

4 10 8
