 Posted: Mon May 07, 2007 9:11 am Post subject: operator evaluation question |
 |
|
Hi,
I see the following description in <<Expert C Programming>>,
the order is defined for && and || and a couple of other operators.
These 2 evaluate their operands in a strict left-to-right oder,
stopping when the result is known.
Is this really true? I think the order is compiler dependent.
Thanks. |

The Standard mandates the order and the short-cut evaluation.
Implementations have no leeway in this regard.
