Problem with GCD of Two Numbers


I’m trying to find the greatest common divisor (GCD) of two numbers. I’m following the instructions from this article.

I’m using the following code to find the GCD:

int gcd(int a, int b) 
    if (b == 0) 
        return a; 
    return gcd(b, a % b);  

The problem is that when I try to run the code, I get a runtime error. I’m not sure what I’m doing wrong - can someone please help me out?

Thanks in advance!

I believe that you have the incorrect forum. This forum deals with Web of Things.
