I know that it wasn't a valid expression in C. It wasn't supposed to be. 
I wasn't writing code. I was doing the math... i.e. I was trying to show 
my thinking that led to an answer of 6 by substituting the values of a 
and b into the equation and working out the math.

I posted that, before I saw your reply regarding post & pre increments. 
Thanks for the explanation. I get it now. :)

I just did that. However, that only verifies that James was correct about 
the result being 5. Running the code didn't explain *why* it was 5. You 
and James did that. :)
