Scoped Enumerations

Explore the differences between classical and scoped enumerations in Modern C++. Understand how scoped enumerations avoid implicit conversions to int, restrict scope pollution, and enhance type safety. This lesson helps you handle enumerations effectively in safety-critical embedded systems programming.

We'll cover the following...

Enumerations conveniently define integer constants with names. These integer constants are called enumerators. Let’s go over some of the drawbacks of using classic enums.

Drawbacks of Enumerations in Classical C++

A short reminder. Three drawbacks of enumerations:

  1. The enumerators implicitly convert to int.
  2. They introduce the enumerators in the enclosing scope.
  3. The type of the enumeration cannot be
