Hi guys, seasons greetings.

I am doing a little exercise on recursion. This piece of code lists an array in reverse order.

Code:
//Chapter 6: Programming Exercises Question 12

#include <iostream>

using namespace std;

int func (int x[], int lo, int hi);

int main()
{
	int intArray[] ={1,2,3,4,5,6,7,8,9,10};
	int length = 10;
	int low = 0;
    int high = 9;

    cout<<func(intArray,  low, high);

	return 0;
}

int func (int x[], int lo, int hi)
{
    if(lo <= hi)
     {
       func( x,  lo+1,  hi);
       cout<<x[lo]<<" ";
     }
}
It works fine. Just when I get the print out, it has a number at the end.
eg,10 9 8 7 6 5 4 3 2 1 4416752

what is the "4416752"? where is it coming from? even if i tell it only tp print one number from the array, it appears after the numeber.

any ideas?
