In fact a useful feature of switch statements with enumerations is that if no default statement is included for the switch, and not all values of the enum have been utilized, the compiler will issue ...

There is no built-in to iterate over enumeration. But there are several ways for enum with only consecutive values: enum E { Begin, E1 = Begin, E2, // .. En, End }; for (E e = E::Begin; e != E::End; ++e) { // Do job with e } C++11 with enum clas...

Scoped enumerations: ... enum class Status; // Forward declaration Status doWork(); // Use the forward declaration ... enum class Status { Invalid, Success, Fail }; Status doWork() // Full declaration required for implementation { return Status::Success; } Unscoped enumerations:...
