Why do we need enum class over enum type?
Enums or Enumerated type (enumeration) is a user-defined data type that can be assigned some limited values. These values are defined by the programmer at the time of declaring the enumerated type. Need for Enum Class over Enum Type: Below are some of the reasons as to what are the limitations of Enum Type and why we need Enum Class to cover them.
When do you need to instantiate an enum?
You cannot instantiate an Enum, thats the whole point of having an Enum. For example you would use enum when defining properties of some thing which would never change like: Now if you want to get the value of the enum, you can use valueOf method of enums.
When do you use enumeration in a C program?

The keyword “enum” is used to declare an enumeration. Here is the syntax of enum in C language, enum enum_name {const1, const2….. }; The enum keyword is also used to define
How to get all enum values in Java?
Your current code just checks if it is an Enum without specifying what type of Enum it is a part of. Because you haven’t specified the type of the enum, you will have to use reflection to find out what the list of enum values is. This will return an array of Enum objects, with each being one of the available options. or MyEnum.values () ?
How is the enum.getvalues method used in pets?
The assembly is loaded in a reflection-only context, a Type object that represents the Pets enumeration is instantiated, an array of FieldInfo objects is retrieved, and the field values are displayed to the console. Retrieves an array of the values of the constants in a specified enumeration type.

Can you use enum classes as type-safe bitmasks?
As it turns out, we can use C++11 to implement our type-safe bitmasks. Strongly typed enums, a.k.a enum classes can help us here. Since enum classes do not implicitly convert to integers, the above code does not compile.
Are there any type safe bitmasks in C + + 11?
