In 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 and only requires that the modifications of an object be ordered with respect to each other and to reads of the same object to.. computation of the assignment expression. So while being ordered was not sufficient to make the behavior defined in C 98 C 11.. in C 98 C 11 has changed the requirement such that being ordered i.e. sequenced is sufficient. And it seems to me that the extra..
