Is it really necessary to use hexadecimal at all in the article? Decimal works just fine for pointers, it's just not conventionally used.

I went back and forth on this and decided in the end that it makes sense to use hex for 2 reasons:

1. It's what people are going to be exposed to in any material outside of this post. 2. Within this post, it helps distinguish between pointers and sizes/values.
