comp.lang.c FAQ list · Question 3.3

Q: I've experimented with the code

int i = 3;
i = i++;
on several compilers. Some gave i the value 3, and some gave 4. Which compiler is correct?

A: There is no correct answer; the expression is undefined. See questions 3.1, 3.8, 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, i+=1, i++, or ++i, not some combination. See also question 3.12b.)
