Here's what I've come up with so far:

#include <iostream>

bool IsPrime(int num)
{
if(num == 0)
return true;

num = abs(num);

I need to write a main() function, that loops over a bunch of
numbers from 0 to 100, calls another function called isPrime() for each of them, and print out the numbers that are prime.
I'm new to...
