Practicality, readability, and - most importantly - consistency are what style guides are based around. What they "should" be based on, in your proposition, is entirely your opinion.

I will, given the option, write around using the post-fix operator, as well as use it in trivial examples such as OPs. Preference has everything to do with it, that's entirely what a style guide is based on.

I prefer to always use the postfix operator. To me it is more important to have easy to read code than succinct code, and I also think the prefix one is uglier, so there's that.

All the pros use Hungarian 😎😎😎🚬

Even if the rest made sense, isUgly is always true

I always prefer books when learning new languages. I just went on a perusal on Amazon for about three hours honing in on a C# .NET book I wanted.

If you'd like a starting place, I rarely am anything but satisfied with the O'Reilly Media books.

EDIT: Also; looking for a BASIC tutorial, eh?
