Hi Pete,
Different languages have different evaluation orders for processing "and" and "or" logic in a condition? I always thought the left to right process of handling a condition was standard across the board. I'm curious what these are (and really, why is it different). One nice thing about being a programmer is that logic is logic, and all we need to move from one language to another is to pick up syntax (not a new method of logic). This has me curious.

It makes it a lot clearer to read (to me), especially if the comparisons
get a little complex with multiples ands/ors.
In addition to being more readable, I figure if something gets changed
in the compiler, my code will still work. It's good defensive
programming and eliminates the need to remember the evaluation order for
different languages.
