Exceptions
EXP08EXP05-EX0: The postfix increment and postfix decrement operators (++ and --) assign a new value to a variable and then subsequently read it. These are well-understood and are an exception to the rule against reading memory that was written in the same expression.
EXP08EXP05-EX1: The logical operators || and && have well-understood short-circuit semantics, so expressions involving these operators may violate this rule. Consider the following code:

EXP30-C. Do not depend on order of evaluation between sequence points | ||||
EXP30-CPP. Do not depend on order of evaluation between sequence points | ||||
