Is using unsigned integer overflow good practice?

Question

I was reading the C Standard the other day, and noticed that unlike signed integer overflow (which is undefined), unsigned integer overflow is well defined. I\'ve seen it us

Answer 1

One way where I could think of unsigned integer overflow causing a problem is when subtracting from a small unsigned value, resulting in it wrapping to a large positive value.
