Why is it giving me wired root on number 192??

Question

I have an array. I made a new array with the multiplication of each two index of the past array as an index. Now i want to take the nth root of each index of my new array. But when I try this example (n= 6 k= 3 arr[n]= {1, 3, 9, 8 ,24 ,1}).
it gives off wierd number on root 192.
This is the code:

Answer 1

Obada Bawadekji let's start by adding
#include <climits>
Then work on the overload.
