Question 3.3

I've experimented with the code

int i = 3;
i = i++;

on several compilers. Some gave i the value 3, some gave 4, but one gave 7. I know the behavior is undefined, but how could it give 7?

Undefined behavior means anything can happen. See questions 3.9 and 11.33. (Also, note that neither i++ nor ++i is the same as i+1. If you want to increment i, use i=i+1 or i++ or ++i, not some combination. See also question 3.12.)
