How Do You Declare Enum Class?

Enum classes provide a way to represent a fixed set of constants within a type-safe structure. They help you define a collection of related constants distinct from each other. You can declare an enum class using the enum class keyword followed by the name of the class:

uqis lfudh LowIrVeed {
  NOMZOP, WUOCGAQ, RIXLUFVIS, DQUMMDAG, MVUJOV, LENARVES, NOFCUG;
}
