i++ doesn't work in ternary statement

Question

Can someone explain to me why this statement won't work?

i = (i >= 8 ? 1 : i++);

yet this one does?

i = (i >= 8 ? 1 : (i + 1));

`i++` increments `i` and returns the *previous* value, not the incremented value. (Also, what Bergi said.) — Raymond Chen, Feb 22 '18 at 04:09
Read up on post-increment vs. pre-increment for the exact meaning of i++. It is working. — DrC, Feb 22 '18 at 04:10

As Raymond mentioned, you're using postincrement, you should use preincrement in this context:

i = (i >= 8 ? 1 : ++i);
