Would this be a case of modulo saving the day?

Like: If Number modulo 2 = 0, true

This has to be taken out of context

Thanks to goodness, finally. A (giggle & snort) solid algorithm. There ya’s go set yer clocks & go get a haircut.

Ffs just use a switch. It's much faster!

This joke was not written by the dude pictured. The author wrote a book of funny code jokes.

this is like the making chess one

This is what Test Driven Development looks like

bool isEven(int value) {
  return (int)(((double)value / 2.0) % 1.0) * 100) != 50;
} 

To be fair, the question is "Write a function that simultaneously determines if the number is even and works as a timer"

assert IsEven(-2);

I hope that the language's ints are at most 32 bits. For 8 bits it could even be written by hand & the source code for a 32 bit version would only take up avg_line_len * 4GiB space for the source code of the function. But it might take a bit of time to compile a version that supports the full range of 64 or 128 bit ints.

that's some good code right there

You could use a loop to subtract 2 from the number until it equals one or zero

private?

IMO he's ragebaiting
