Message: [QUOTE="Richard Heathfield, post: 2915491"] Chris Dollin said: Neither the C abstract machine nor the Standard impose an order of evaluation on the implementation. For example, 2 * 2 + 2 need not result in any additions or multiplications being carried out. The implementation could easily code this as (2 << 1) | 2 if it wanted. Or even as 6, with no runtime evaluation happening at all! Right - it doesn't determine the order of those operands. Neither does it determine the *order in which they are evaluated*. Oh, attack away, my dear chap - with any luck, you'll prove I'm wrong, and then I'll have learned something. [/QUOTE]
