i just want to recursively call each digit from a number and print its name

#include
#include

using namespace std;

int digits(int n)
{

if(n/10==0)
return 0 ;

digits(n/10);

return n%10;

}

int main()
{
string arr[10] = {“zero”, “One”, “Two”, “Three”,”Four”,”Five”, “Six”, “Seven”, “Eight”, “Nine”};
int n;

cin >> n ;
cout << endl;

cout << digits(n) << " -> " << arr[digits(n)];

}
