Say I have something like
int x = 5;
x = x++;
Is this undefined behavior in C? I have gotten a few conflicting answers on whether or not this is defined.

There is one thing undefined here and that sir is `x`. :P – no more sigsegv Dec 15 '21 at 20:27

Yes, the behavior is undefined. There is no well-defined result for the value of `x` or the behavior of the code in general. – John Bode Dec 15 '21 at 23:30
