Recursion exercise

[BushMaster]

Hi guys, seasons greetings.

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


//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?

Hi!

At least your code has one error. The func function is protyped to return an int. You dont return anything.

Try adding return 0 at the end of that function.

And change this line;

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


to this;

func(intArray, low, high);

Thanks, that seems to have solved it.
