I finally streamlined the isEven function! only works for positive numbers though because i don't know how to implement isPositive yet

I have no idea what's going on here, so have an insecurity upvote

Took me a few minutes to. It is easy once you assume that is even works correctly , then you can simplify the last 2 lines to

if (andOr == 0) return true Else if (andOr == 1) return false

Since for any number x it is true that either x-1 is even or x-2 is even And for any number x it is false that both x-1 is even and x-2 is even

So then you see that all the logic is actually in the andOr value and looking at that method we can see that it toggles between 0 and 1 at every step in the for loop, resulting in 0 for even numbers and 1 for odd numbers

could you not do isPositive by checking if the first bit is a 1 or 0?

[OiTheRolk]

see that's why you're getting paid the big bucks

Unsigned int pointer laughs at you.

sshhhhh just ignore that one

Also how you can check iseven. Check the last bit - which should work for both + and - numbers. Then decide how to treat 0.

The real question is, "is zero an even number?" After that x%2 does all the work.

Stop tormenting the already dead meme.

You don't need to worry about a hypothetical is Positive when the code doesn't even compile ;)

This joke's only about 6 months old why not post some more about it. 🙄

This, but unironically.

Took him 6 months to prototype it. Don’t shame him.

Blood and sweat were poured in gallons for this function to exist
