C++ Enums

This lesson is part of C++ · All levels

Summary

This lesson discusses enumeration, which is how to define a set of named constants that makes code more readable. For example, status or days of the week are more clearly written as names than as normal numbers. Modern C++ also provides a more secure enum class because of its scope and ease of conflict.

Key points

Enum defines a set of named constants in a type.
By default, the first enum is 0 and then one.
The initial value of the enum can be set explicitly, e.g. the enum E {A = 1, B = 5};.
Enum class (C++11) is scope-sensitive and requires cast, so it's safer.
