This completely removes the need to think about short-circuit evaluations. +Increment/decrement operators +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Increment and decrement operators may never be used inside larger expressions. +Their usage as expression-3 of a for loop is considered as an entire expression +and doesn't violate this rule. The rationale is to avoid tricky errors related +to sequence points. Since such operators may not be used inside larger +expressions, there is no difference between prefix and postfix operators. +The latter are preferred because they look more object-oriented, somewhat +matching the object.method() syntax. + SEE --- |
