I'd like to make StructOpt work with enums such that every time a user passes -d sunday it'd parsed as a Day::Sunday:
A footnote in the standard implies that any enum expression value is defined behavior; why does Clang's undefined behavior sanitizer flag out-of-range values?
I am used to using enum as constants -- they're quick to write, can be placed in .h files, and work fine.
Consider:My understanding is that the scoped enum needs to be cased into the underlying type or integer, and then it can be applied to operator < > ==. But it looks like the code snippet above can work without any explicit overloading operator <.

I'm trying, and failing, to retrieve all Enum values and place them in a list using Java 8 and streams. So far I've tried the two approaches below, but neither one returns the value.
I want to fully understand how a C++ compiler deals with an enum exceeding the largest possible number, i.e., containing -1 and UINT64_MAX the at the same time, i.e.
I have the following interface:that is implemented by my enums (I omitted the constructor and methods implementation)
I want the user to enter a number from 1 to 7. If the number is 1, print that it is a Monday. If the number is 2, print that it is Tuesday, etc.
I have an enum with descriptions as String. This is the enum.Now, if I need the data for A, I'd just do
