#include<iostream>

using namespace std;

void copy(int l1[],int l2[],int index)
{
   //just return if index<0
   if (index < 0)
   {
       return;
   }

   else
   {

       l2[index] = l1[index];

       index = index - 1;

       //recursive call
       copy(l1, l2, index);

   }
}

int main()
{
   //create two arrays
   const int size = 4;
   int l1[size] = { 10,20,30,40 };
   int l2[size] ;

   //call recursive function to copy l1 to l2
   copy(l1, l2, size - 1);

   //print l2
   for (int i = 0; i < size; i++)
   {

       cout << l2[i] << endl;
   }

   system("pause");//remove it if not required.it is used to prevent console in visual studio from closing
   return 0;

}
