C uses "&" for the address-operator because 'ampersand sounds like "address"'

Note that gcc and clang will warn you about fallthrough statements i you use -Wextra and that you have to either have insert a /fallthrough/ comment to make your intent clear.

Pity the (wo)man who does not use -Wall -Wextra for (s)he is truly mistaken

Clang actually doesn't warn in -Wextra:

It requires the separate option -Wimplicit-fallthrough:

(which tbh sounds like a bug, because usually Clang tries to emulate GCC behaviour)

C++17 now has standardized the [[fallthrough]] attribute:

(For backwards compatibility, it still must fallthrough with or without the attribute; the attribute just signals programmer intention and silences the warning.)
