### Re: Halting Problem

We want to prove that a halting oracle program can't exist, by showing that one existing would lead to a contradiction. The naive way to do this is to write a program that calls the oracle on our program, and halts if the oracle predicts it won't, and loops forever otherwise. However, we can't have ...

### Re: Halting Problem

Our program calls willHalt. willHalt takes a program and data determines if the program will halt if called with that data. It does not necessarily have to call the program do this, all that matters is that willHalt returns true or false correctly.

Since 2 is even, and 2 = 1, then 1 must be even.
