For i = 0, why is (i += i++) equal to 0?
...ough decomposition of i += i++ to the parts it is made of requires one to know that both += and ++ are not atomic (that is, neither one is a single operation), even if they look like they are. The way these are implemented involve temporary variables, copies of i before the operations take place - o...

What happens if you static_cast invalid value to enum class?
...ct 1766.
The [expr.static.cast]p10 paragraph has been strengthened, so you now can invoke UB if you cast a value that is outside the representable range of an enum to the enum type. This still doesn't apply to the scenario in the question, since data[0] is of the underlying type of the enumeration (...
