Ooooo, fancy placing the divide by zero. Smart thinking!

quick question from a newbie...... how am i supopost to know? I mean I can google my way trouth the solution but isn't that cheating? Is there a better way to find this stuff out or do you all just google things?
Thanks for any answer :)

BIG HINT and advice (didn't think it was necessarily a spoiler since a bit of assistance in this nature isn't a solution per say, but open to opinions otherwise):
Very tricky at first as I was confused why my array was looking at previous attempts and finding repeating values, but it might be because the pointer pointed to by unitialized array was being referred to over and over. Make sure you initialized your array (if that's the method you choose, similar to hashtable) every time you call it! ;)

Also the stdbool.h file is being included so "true" and "false" work (for those who are confused below).
