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

I rarely use pre-increment tbh, but post-increment all the time for array indices (since typically the array should be indexed with the value before the increment happens).

If the pre- or post-increment behaviour isn't actually needed, I prefer `x += 1` though.
