What in particular do you need help with?
(Your question?)

I was just wondering if you guys saw any bugs?

One too many '}' for your first while loop.
Delete line 77.

Also your function deadNum, seems to be complaining about have a return.
Possibly the while loop may be initiating the return function below it?
Possibly apply {} after the while loop? Unless you intend to apply return during each of your while-loops cycle; if so add a return after your already implemented return.

while ((int)pow(2.0, ++i) < n)
	return ((int)pow(2.0, i) == n + 1);


You can't return multiple times.

@giblit
how would i fix that?

Well what exactly are you trying to do? If you want to increment i until i2 is greater than or equal to n then you want a semi colon on that line.
