c++ Programming Glossary: sufficientIn which versions of the C++ standard does “(i+=10)+=10” have undefined behaviour? http://stackoverflow.com/questions/10655290/in-which-versions-of-the-c-standard-does-i-10-10-have-undefined-behaviou defined in both C 98 and C 11 however in C 98 this is not sufficient to make the behavior defined. In C 98 multiple modifications.. and so the fact that it consists of two modifications is sufficient to render its behavior undefined. C 11 doesn't have sequence.. the order is specified it appears to me that this is not sufficient for defined behavior in C 98. C 11 C 11 does away sequence points..
