Inside the main() method, specify the enum keyword, followed by the name of the enum (Level) and then the name of the enum variable (myVar in this example):enum Level myVar; Now that you have created an enum va
Enumerations are determined using the keywordenum, and they can optionally define a name for the type (e.g.Colorin the following code snippet). Note that the C++ enumeration constants have implementation-defined integral types. So if the given values need larger space than theint, the correspond...

What is enumeration (enum) in C++?It is a distinct type of set of values, whose values come between ranges of values.Reference: http://en.cppreference.com/w/cpp/language/enumDeclare/define enumerationWe can declare/define "enumeration/enum" given as below:...
underlyingValue(cppEnum) returns the underlying numeric value for a C++ enumeration object created in MATLAB®. underlyingValue is an instance method of the enumeration. exampleExamples collapse all Display Underlying Color Value Create a file enums.hpp with these statements. enum class COLOR { RED...
With normal enumerations, enumerators are placed in the same scope as the enumeration itself, so you can typically access enumerators directly (e.g. red). However, with enum classes, the strong scoping rules mean that all enumerators are considered part of the enumeration, so you have to use...
If the enumeration is unscoped, the underlying type is an integral type that can represent all the enumerator values defined in the enumeration. For example: // the underlying type is "unsigned int" enum Colour : unsigned int { orange = 0, green = 1, purple = 0x02U }; ...
