FWIW, some guy named Dennis Ritchie says this is not true.
"People often guess that [++ and --]were created to use the
auto-increment and auto-decrement address modes provided
by the DEC PDP-11 on which C and Unix first became popular.
This is historically impossible, since there was no PDP-11
when B was developed."
"B" is the language from which C inherited ++ and --, and much else.
