Important reminder just in the Preface :-)

Takeaway #1: "C and C++ are different: don’t mix them, and don’t mix them up"

Bjarne should have called it ++C.

Because people choose to use pre-increment by default instead of post-increment?

Why is that?

Why would you use post increment by default? The semantics are very particular.

Only on very rare occasions I need post increment semantics.

And in those cases I prefer to use a temporary to make the intent more clear

If you're used to the idiom, the intent couldn't be clearer.

I miss it when switching between C/++ and other languages.
