> I think, that this is wrong. The exact rule should be more like "...if > the result of the operation is not defined by standard..." The exact rule is in section 5.1.2.3 Paragraph 2 "Evaluation of an expression may produce side effects. At certain specified points in the execution sequence called sequence points, all side effects of previous evaluations shall be complete and no side effects of subsequent evaluations shall have taken place." Since there are no sequence points for the assignment, increment or index operators, the behaviour is undefined. Regards, Ryan Mansfield
